R O A S S O C I AT E S

Founded in 1963 by Dr. Robert Okada, RO designed the first commercial 20 KHz switching power supply, the 5V 10A Model 210 in 1967. Applying dedication to quality and technology for the past 40 years, RO continues to design and manufacture a complete line of high efficiency, high quality DC-DC converters from 40-600W and AC-DC PFC modules from 600-1000W for use in telecom, industrial, commercial, and quasi-military applications. In 1988, RO entered the high density converter market as the trend to "distributed component power" and "centralized component power" began to take off. Our 200-250 Watt MicroVerter family of DC-DC converters set the standard for high density with its revolutionary 58 W/cubic inch and its unique 185W triple output. Since then we have introduced a variety of new products, including the 100-120 Watt NanoVerter family, the 50-60 Watt PicoVerter family, the 400-600 Watt MegaVerter family, the 50-240 Watt SuperVerter family, the 85-110 Watt SuperVerter Dual family, the 600-1000 Watt AC-DC PFC UniVerter family, the 80-250 Watt high efficiency SyncroVerter family, and most recently the 80-115 Watt QuattroVerter family. The success of RO has been based on the quality and reliability of its products, as well as the personal service given to its customers. RO has been a power technology leader since 1963. NEW MANUFACTURING FACILITIES RO has a state-of-the-art Surface Mount Technology manufacturing facility plus Automatic Test and Burn-In located in Sunnyvale, California. In addition, RO has two off-shore licensees capable of producing high volume, low cost products under technical license.

GENERAL DESCRIPTION RO DC-DC and AC-DC converter modules have proven to be extremely rugged and are designed to meet MIL-STD-810D requirements. Also, once they are installed properly on a printed circuit board, they can take all the normal mechanical forces for circuit boards and circuit board mounted components. Reasonable care must exercised, however, during all handling of converter modules, to prevent mechanical damage to the case or the electrical terminal pins.

off the board. While the pins are clearing the sockets or circuit board holes, the plane of the module baseplate must remain in parallel with the plane of the circuit board. Otherwise, the pins may be over stressed or bent resulting in degradation or failure. SHIPMENT OF MODULES In the event that individual modules are shipped as a component and not in a circuit board assembly, adequate protection must be provided to the pins to prevent damage. Utilization of the original plastic shipping tube from RO is recommended.

IMPLEMENTATION RELATED TOPICS STORAGE Modules should be kept in their original shipping containers to provide adequate protection until inserted into printed circuit boards. INSTALLATION INTO PRINTED CIRCUIT BOARD Reasonable care must be exercised when inserting the pins of a module into the holes or sockets of a printed circuit board during production or prototype fabrication. The pins must all be properly aligned with the holes or sockets before pressure is evenly exerted to the surface of the module to seat it onto the board. Otherwise, overstressed or bent pins could result in external pin breakage, internal damage, or degradation of the module. REMOVAL FROM PRINTED CIRCUIT BOARD In soldered applications, solder must be carefully removed from the pin/pad connections and each pin must be observed to be mechanically free from its pad. Once the solder is adequately removed, or for socket applications, the module must be removed using both hands, one on either end of the module, to carefully lift the module evenly AP-2 Mechanical Mounting Considerations

CONTINUED GENERAL DESCRIPTION RO DC-DC and AC-DC converter modules have proven to be extremely rugged, and are designed to meet MIL-STD-810D requirements. Also, once they are installed properly on a printed circuit board, they can take all the normal mechanical forces for circuit boards and circuit board mounted components. Reasonable care must be exercised, however, during the design and fabrication of modules into power supply assemblies to prevent excess stress that could cause mechanical damage to the case or the electrical terminal pins. ASSEMBLY Good manufacturing procedures must be observed in assembling modules into power supply assemblies to prevent excess stress on the modules or pins. Reasonable care must be exercised in inserting (and removing) modules from printed circuit boards (See AP-1, Module Handling Considerations). In particular, care must be exercised in applications where a single heat sink is attached to more than one module in a soldered application. If possible, the heat sink should be assembled to the modules prior to soldering. In situations where this is not possible, care must be exercised to insure that bolting of the modules to the heat sink following the soldering operation does not result in excess stress on the pins. One approach might be to fixture the modules during soldering to insure their baseplates are co-planer and to also insure that the heat sink is flat and that pin forces are reasonable during and after assembly.

IMPLEMENTATION DESIGN Good mechanical engineering practices must be observed in designing modules into power supply assemblies to prevent excess stress or bending forces on the modules and their electrical terminal pins. Circuit board holes and sockets must be properly located and mechanical attachment to heat sinks and circuit boards must be designed to prevent excess shear, compression, or tensile forces on the pins. (See AP-19, Hole Dimensions and Socket Information.)

GENERAL DESCRIPTION Output voltage trimming allows the user to change the output voltage of the module. This greatly enhances the functionality of modules by allowing a few select, standard modules to be applied to virtually any application; regardless of the voltage requirements. This allows module users to reduce the number of models kept in stock. This application note covers the basics of trimming all RO modules available as of June 2002. The format of the trim equation has been modified so that a single trimming equation can be used. The equation parameters for a particular module can be found in the relevant parameters table. Page QUATTROVERTER Trimming Parameters 59 SYNCROVERTER Trimming Parameters 60 SUPERVERTER DUAL Trimming Parameters 61 SUPERVERTER Trimming Parameters 61 PICOVERTER Trimming Parameters 62 MICROVERTER Trimming Parameters 63 MEGAVERTER Trimming Parameters 63 NANOVERTER Trimming Parameters 64 Also covered, are the effects of trimming on various performance parameters, application ideas for trimming, and important precautions to observe.

output connect a resistor from TRIM to either +SENSE or -SENSE depending on whether you want a lower or higher than nominal output voltage and which type of trimming the module uses. Each of the following parameter tables indicates which type of trimming is used by the module, whether to connect to +SENSE or ­SENSE, and the parameter values to enter in the trim equation. The figures accompanying the tables show the appropriate connections. To calculate the resistor value use the following equation:

Where: A and B = The equation parameters given in the tables. |V| = The magnitude of the desired voltage change from the nominal output voltage. |V| is always positive.

QUATTROVERTER TRIMMING The trimming parameters for the QUATTROVERTER modules are given in Table 5a. These parameters, along with the desired change in output voltage are plugged into the trim resistor equation:

IMPLEMENTATION BASIC TRIMMING CONCEPTS RO uses a simple approach to trimming modules that in most cases allows the module to be trimmed with a single external resistor. There are two types of trimming used in RO modules: Inverting trim, in which the trim signal is summed in with the sense feedback and Non-inverting trim, in which the trim signal is used to modify the reference for the control circuits. In either case, to trim the module's

The QUATTROVERTER modules use a noninverting trim function. To trim the output voltage UP, connect the trim resistor from TRIM to +SENSE. To trim the output voltage DOWN, connect the trim resistor from TRIM to -SENSE. These connections are shown in Figure 5a.

Several of the module performance parameters will change as the output voltage is trimmed. All specifications given in the data sheets apply over the guaranteed adjustment range. The specifications of primary concern are: efficiency, output ripple, and output OVP . Efficiency ­ The efficiency of a given model will decrease as the output voltage is trimmed down and increase as the voltage is trimmed up. Output Ripple ­ As a percentage of the output voltage, the output ripple will increase as the voltage is lowered and decrease as the voltage is raised. Output OVP ­ The OVP set point remains at a fixed voltage, independent of output trimming. In most cases the OVP set point is what limits the maximum trimmable voltage. As an additional note the user must pay attention to the current and power ratings when trimming the output voltage. All RO converters have a fixed current limit. As the output voltage is trimmed down the current limit set point remains constant. Therefore, in terms of output power, if the unit is trimmed down the available output power drops proportionally. Likewise, if the output is trimmed up the available power appears to go up, however, do not exceed the maximum rated output power of the module when trimming the output up.

CONTINUED POSSIBLE APPLICATIONS Eliminating the need for remote sense ­ Output trimming can be used instead of remote sense when the load current change is limited and the voltage drop between converter and load is relatively constant. System testing (margining) ­ Often, it's helpful to test system operation with the supply voltage ­ usually the +5V logic voltage ­ set first at one extreme, then at the other. Any circuitry that fails to perform properly under these manufacturer's test conditions might also fail under conditions found in the user's environment. Margin testing helps insure trouble-free system operation. Obtaining non-standard output voltages ­ When a non-standard output voltage is necessary, it may be available simply by trimming the output voltage of a module with an output voltage that's close to the desired voltage. Although the published data sheet limits are valid for the guaranteed adjustment range, lower output voltages are commonly available by using the trim function. Contact the factory for details. Reducing the number of stocked models ­ When two output voltages are necessary, such as 24V and 28V, one model may be able to supply both, using the trim function to set the lower voltage. Noise sensitivity ­ The TRIM pin is noise sensitive. External resistors (either fixed or variable) should be located within one cm of the converter. If wires are necessary, use twisted or shielded wires. Output power, output current ­ If the output voltage is increased, output current must be derated to avoid exceeding module maximum output power. If the output voltage is decreased, output current is limited to its maximum rating and the available output power decreases. Adjustment range limits ­ In some cases, the output voltage can be trimmed outside the guaranteed adjustment range. However, data sheet specifications are only valid within the specified voltage range.

AP6 REMOTE SENSING

GENERAL DESCRIPTION The remote sense feature provides excellent regulation at the load rather than at the converter's output terminals. It does this by sensing and regulating voltage at the load, compensating for load current IR drops across output connectors, traces, and cables as well as "or'ing" diode forward voltage drops. The remote sense feature will compensate for voltage drops up to 0.5V or 10% of nominal output voltage, whichever is greater. If the total voltage drop between output terminals and load exceeds this amount, other design changes, such as increasing conductor size or decreasing connector resistance, must be taken. RO has also recommended diodes for or'ing applications that minimize forward voltage drop. Please see AP13 for details. Voltage drops across output series resistance ("IRdrops") vary with output current. If the load current stays relatively constant, RO recommends using output voltage trim instead of remote sensing. (See AP5) (Output voltage trim increases the output voltage by a fixed amount to compensate for IR drops between the module and the load; remote sense increases the output voltage dynamically to compensate for variable IR drops due to load current changes.) Voltage drops across or'ing diodes (diodes that isolate one converter's output from another paralleled converter's) tend to stay relatively constant with load current variations, but change with diode temperature. RO recommends using remote sense when using or'ing diodes if precise regulation is needed. IMPLEMENTATION The remote sense terminals must always be connected, either to the output terminals or to the load. Connect -SENSE to -OUT at the load and +SENSE to +OUT at the load as shown in Figure 6a. To reduce noise susceptibility, parallel an electrolytic capacitor and small ceramic capacitor across the remote sense terminals where they are connected to the load as shown in Figure 6a. (Tantalum may be used in lieu of electrolytic capacitors) Please refer to Table 6-1 for recommended values. Noise filter capacitors are especially helpful when the remote sense leads are over one foot long.

RELATED TOPICS AP-5 AP-7 Output Voltage Trimming Measuring Line and Load Regulation

PRECAUTIONS Improper use of the remote sense feature can introduce noise into the module's feedback loop, resulting in output noise or oscillations. There are several ways to minimize remote sense lead noise pickup. (a) Use shielded and/or twisted leads for remote sensing. Also consider using coax cable. (b) Use noise filter capacitors connected across the remote sense leads at the load. See Figure 6a and Table 6-1 for further information. (c) Use output voltage trim to make up for IR drops instead of remote sense if the load current does not change appreciably. (See AP5) If the sense leads fail open circuit, the module output voltage will rise to the OVP set point. If there is any possibility of this situation, connect a 100W resistor from +OUT to +SENSE, and from -OUT to -SENSE. Be careful not to reverse the sense leads. If reversed, the module will be damaged. RO recommends using keyed connectors.

AP7 MEASURING LINE A N D LOA D R E G U L AT I O N

GENERAL DESCRIPTION Line regulation is the module's ability to maintain a constant output voltage as the line (input) voltage changes. Load regulation is the module's ability to maintain a constant output voltage as the load current changes. Line and load regulation are two of the most common types of converter measurements. Although straightforward, there are some simple guidelines that will help insure accurate readings. To check the module for regulation, measure the output voltage at the sense pins (+SENSE and -SENSE). There is virtually no current flowing through the sense leads, and consequently no appreciable drop across them. Therefore, measuring at the sense pins is equivalent to measuring at the point where the sense leads are connected to the output leads. In contrast, there can be a significant voltage drop between the module's output terminals and the load. This voltage drop, which varies with load current, can cause erroneous regulation values. The remote sense terminals should always be connected to the output either at the output terminals or at the load. (Connect -SENSE to -OUT and +SENSE to +OUT.) Line Regulation: Connect a DVM to the sense terminals. Vary the input voltage from minimum to maximum. The output voltage change, as a percentage of nominal output voltage, is the line regulation. See Figure 7a.

AP8 MEASURING OUTPUT NOISE AND RIPPLE

GENERAL DESCRIPTION Accurately measuring output noise and ripple requires a basic understanding of the high frequency nature of noise. Very often, "noise" (as commonly measured) is actually the vector sum of common and differential-mode noise. Common mode noise is common to both outputs (that is, to +OUT and -OUT) with respect to chassis or earth ground. Differential mode noise is found at one output with respect to the other. While the system load can be affected by differential mode noise, it is seldom affected by common mode noise. The latter is often only created in the process of measuring the former. Noise can be measured as RMS or peak-topeak. Low frequency noise with a low peak-toaverage ratio is often measured as RMS. High frequency spike noise is more meaningfully measured with an oscilloscope as peak-to-peak noise. The following information pertains to measuring high frequency spike noise.

USING AN OSCILLOSCOPE PROBE If an oscilloscope probe must be used, it must be properly prepared for high frequency measurements. The greatest error source is usually the unshielded portion of the oscilloscope probe. Error voltages induced by magnetic radiation in the loop can easily swamp out the actual values. To reduce measurement errors, keep unshielded leads as short as possible. Prepare the probe for high frequency measurements by first removing the clip-on ground wire and the probe body fishhook adapter. Attach a special tip and ground lead assembly as shown in Figure 8d. These assemblies are available from several manufacturers: · Hewlett Packard · Kikusui · LeCroy

Determine if there is any common mode noise by simultaneously contacting the probe tip and ground lead to the -OUT pin. Any scope pattern indicates common mode noise, and must be eliminated before accurate measurements can be taken. To eliminate the noise: · Wrap the oscilloscope probe lead several times around a large-diameter ferrite toroid. This will act as a balun, or common mode inductor. It increases common mode impedance without significantly increasing differential mode impedance. · Isolate the oscilloscope power source from the line voltage with an isolation transformer, or · Wrap the power source AC line cord several times around a large-diameter ferrite toroid. This also reduces common mode current. · Try using another oscilloscope and/or probe

PRECAUTIONS Do not use the ground lead clipped to most common oscilloscope probes. The loop of wire itself will pick up high frequency radiated noise and give erroneous readings.

GENERAL CONSIDERATIONS Thermal management is an important part of the system design process. The superior designs of RO's modules make thermal management relatively easy. Their high conversion efficiency minimizes the necessary cooling while their small package sizes with large thermal interfaces allow simultaneous reductions in system size and cost, along with substantial improvements in reliability. This application note presents some guidelines for good thermal design of systems using RO converters.

HEAT REMOVAL MECHANISMS OF TRANSFER Heat is removed from RO converters through the module's baseplate. The baseplate is thermally coupled to and electrically isolated from all internal components. The goal of good thermal design is to transfer heat from the baseplate to the outside world; thereby keeping the baseplate temperature below the maximum rating. Heat energy is transferred from warm objects to cold objects by three fundamental means: Convection: The transfer of energy through a liquid or gaseous media. Conduction: The transfer of energy through a solid media. Radiation: The transfer of energy between masses at different temperatures via predominantly infrared wavelengths. While all three transfer mechanisms will be present in every application, convection is the dominant means of heat transfer in most. However, some consideration should be given to all three transfer means to ensure the cooling design is successful. BASEPLATE TO HEATSINK INTERFACE In many applications, heat will be conducted from the module to a heatsink, which is then cooled via one of the three mechanisms mentioned above. The interface between the heatsink and the baseplate can be modeled as a "thermal resistance" in series with the dissipated power flow. The temperature differential across the interface can be considerable if appropriate measures are not taken. These measures include controlling the flatness of the two surfaces and using a filler material such as thermal compound or Grafoil®. With proper care, the thermal resistance across the interface can be less than 0.8 °C·in2/Watt; which for a 3.6" x 2.4" module is less than 0.09°C/Watt.

MODULE LOSSES AC-DC and DC-DC modules convert power from an input source into regulated power suitable for the given application. While RO's conversion efficiencies are high, they are not perfect, and some of the input power is lost as heat in the module; which can be calculated from the following equations:

PMOD = POUT X

­1

This equation is derived from the definition of efficiency:

POUT = PIN

The very first step in all thermal management designs is to estimate the worst case power dissipation. This can be estimated from the module efficiency graphs given in the catalog; or for conditions not covered by the graphs, it can be directly measured.

CONVECTION COOLING Convection cooling is by far the most popular form of cooling used. In a convection cooled system the heat energy is transferred from the module to a nearby body of air either by direct contact or via a heatsink attached to the module baseplate. The thermal model for convection cooling is shown in Figure 10a. The baseplate temperature depends on the internal power dissipation, the total thermal resistance from the baseplate to the ambient air, and the ambient air temperature. The interface resistance can be minimized as discussed previously. The heatsink-to-air resistance is dependent on a variety of factors including heatsink material, geometry, and surface finish; as well as air temperature, air density, and air flow rate. Fortunately, thermal resistance data is available for a very wide range of standard heatsinks (from RO, Aavid, Thermaloy, and others) for use in convection cooled applications. Convection cooling is usually classified into two types: natural convection, and forced air convection.

AMBIENT AIR TEMPERATURE (TA) HEAT FLOW

unobstructed path for the air to flow. Since the hot air rises vertically the module and heatsink fins must be properly oriented in the vertical direction to maximize airflow. The advantages of free air convection cooling over forced air cooling include a lower implementation cost (no fans), and higher cooling system reliability. The heatsink volume, however, will have to be larger to achieve the same baseplate temperature as with forced air convection. Forced air convection can make a big difference in cooling effectiveness. With a suitable heatsink, the heatsink-to-air thermal resistance can be improved by as much as an order of magnitude when compared to natural convection performance. Forced air implies the use of fans. In many applications, fans must be used to achieve some desired combination of overall system reliability and packaging density. In other applications, however, fans can't be considered because "dirty" environments require filters which must be changed regularly to maintain cooling efficiency. Neglecting to change a filter, or a failure of the fan may cause the system to shut down. The process for selecting natural convection and forced convection heatsinks are essentially the same. For forced air systems, however, a fan must also be selected to create the required airflow, and the airflow must be channeled so that maximum cooling is achieved.

To calculate the required heatsinking: 1. Determine the worst case power to be dissipated. This should be based upon converter efficiency and worst-case converter power output using the formula given in the section on Module Losses. 2. Determine the thermal resistance from the module to the heatsink. An estimate of 0.8 °C·in2/Watt should provide adequate safety margin. For more accuracy, experimentally measure the interface resistance for your application.

Figure 10a: Thermal model for convection cooled systems.

Natural convection, also referred to as free air convection, operates on the principle that air becomes less dense and rises when it is heated. Cooler more dense air then moves in to take its place and remove additional heat. Free air convection only works well when there is an

HA =

Alternatively, steps 4 and 5 can be done in the opposite order if your heatsink constraints are more severe than your fan constraints, i.e. you can select the heatsink first, and then pick a fan to get the necessary airflow. 6. Estimate the baseplate temperature using the following formula:

Table 10a: Thermal resistances of RO heatsinks

When designing the cooling system keep the following in mind: · Heatsink data for natural convection is almost always given for vertical fin orientation. Orienting the fins in any other direction will impede the airflow and degrade the cooling effectiveness significantly. If you can't use the preferred orientation then get relevant heat sink performance data from the manufacturer. · Natural convection depends on air movement caused by air density changes. The manufacturer's thermal resistance data depends on unobstructed air movement in-between and around the fins. If the air movement will be blocked or otherwise affected by the packaging then a larger heatsink may be required. In some cases, natural convection cooling may not be useable. · Radiation cooling can be a significant contributor to natural convection cooled systems. Maximize radiation cooling by using an appropriate finish on the heatsink, such as black anodize.

4. For forced air systems estimate the airflow through the heatsink. This is a non-trivial task and is some-what iterative with step 5 because the heatsink selected will create back-pressure and will affect the airflow. To convert CFM fan data to LFM use the following formula:

LFM =

CFM AreaHS

Keep in mind that only the air that flows between the fins contributes to the cooling of the module. 5. Select a heatsink that meets the thermal resistance, cost, and physical dimension constraints. Keep in mind that every degree that the baseplate temperature is lowered results in significant improvements in the module reliability. You should therefore select the heatsink with the lowest possible thermal resistance within your constraints. Table 10a shows the thermal resistance of RO's heatsinks.

· It is not necessary for the heatsink to be the same size as the baseplate. Heatsinks that are larger than the baseplate can often be used advantageously. Especially in applications where the fin height may be limited. When using heatsinks that are larger than the baseplate, select one that has a thick base for better conduction to the outer fins and derate the manufacturer's thermal resistance slightly. · Several modules can be mounted to a common heatsink, but cooling calculations must now take into account the total power dissipation of all the modules. Give consideration to the possibility of localized overheating if the power dissipation isn't uniformly distributed.

Module Power Dissipation: TIPS ON MODULE PLACEMENT Here are some tips to consider when laying out the system and placing the modules on the PWB: · Always ensure that the module and heatsink interfacing surfaces are flat, smooth, clean, and free of debris · Always use a void filling material such as thermal compound, thermal pads, or some other thermally conductive, conformable or malleable material. RO offers precut thermal pads made from GRAFOIL, material. Note: thermal pads are pre-installed on all heatsinks purchased from RO. · Stagger the modules on the PWB to promote good airflow, to minimize thermal interaction between modules, and to facilitate even heat distribution. · Avoid blocking the airflow to the modules with other components. · Use a heatsink with the fins running in the direction of the airflow. For natural convection systems the air will flow upward in a vertical direction.

The desired baseplate temperature is 75°C and a conservative estimate of the interface thermal resistance is 0.2°C/W. We therefore need a heatsink with a thermal resistance of:

=(75°C ­ 30°C ) ­ 0.2°C/W 33W 1.2°C/W or less

From the catalog we see that the RO 2005 heatsink has a thermal resistance of 1.0°C/W with 400 LFM of airflow. The resulting design will operate at a baseplate temperature of:

TB = 30°C+33W x( 1.0°C/W+0.2°C/W) TB 70°C

PRECAUTIONS Observe Max. Temperature Ratings While the modules will protect themselves if the maximum baseplate temperature rating is exceeded, operating above the rating for extended periods of time can reduce the reliability of the module. Don't Compress PC Board Material Don't allow the mounting screws for the modules to exert compressive force on the PWB. The PWB material, typically G-10 or FR-4, will cold flow away from the screw and release the screw tension. The result can be a loss of heatsinking. See Application Note 19, Hole Dimensions and Socket Information, for further information.

F R E Q U E N T LY A S K E D Q U E S T I O N S

Included here are answers to some of the questions that our customers ask most frequently.

Q: What is the PWB footprint for the RO modules? A: RO's modules are generally smaller than our competition's modules. The basic, recommended PWB footprints for our modules are shown in Application Note 19, Hole Dimensions and Socket Information. In addition, the outline drawings included in the product data sheets are another good source of information for creating custom PWB footprints. Q: How much heatsinking do I need for the RO converters? A: The amount of heatsinking required is determined by the environment that the module is placed in, the heat produced in the module, and the maximum desired baseplate temperature. Because RO's modules are highly efficient the required heatsinking is minimal. It may even be possible to operate the modules without any additional heatsinking. The thermal performance curves in this catalog were designed so that you can quickly determine the amount of heatsinking required for your application. A more in-depth discussion of thermal design with the RO modules is available in Application Note 10, Thermal Considerations. Q: Why is a 1W, 6.2V Zener diode recommended on the Parallel Pin? A: The Zener diode is recommended for any application that can see more than 6V, induced or applied, on the Parallel Pin. Accidental shorting of the Parallel Pin to a voltage greater than 6V will cause the module to fail. A 1W, 6.2V Zener diode will protect against most incidental shorts that occur during module testing as well as most externally induced transients that occur during operation.

Q: Why do I see 1V spikes on the output of the module? A: These spikes do not really occur on the output, rather they are mostly the result of noise pickup and measurement error in the test setup used. A common source of noise pickup is the loop created by the ground clip on most standard scope probes. Application Note 8, Noise and Ripple Measurement, discusses how to properly measure the output noise and ripple. Q: Can RO modules be used with no additional components? A: Yes, in some applications they can. However, bypass capacitors are often required to reduce system noise and achieve proper module performance. For basic systems, we recommend that pads and traces for the components shown in Figure 1 be included in the initial PWB layout. The design team can then either optimize them for performance or, if performance is good, eliminate them for cost reduction.

Q: Paralleling De-coupling Modules (PDMs) are great when redundancy is required, but can the RO modules be paralleled without PDMs? A: Yes, RO modules can be paralleled without any external components other than bypass and storage capacitors when redundancy is not required. An exception to this, however, is the 300V MICROVERTER series; which requires a disconnect circuit to ensure an orderly startup. See Application Note 11 for more information.

F R E Q U E N T LY A S K E D Q U E S T I O N S

CONTINUED Q: What is the recommended solder process for the modules? A: The recommended solder process is a wave solder process with the solder wave at 260°C. Each pin should be in the wave for 5 seconds and the big pins should enter the wave last. Because the modules have a high thermal mass, the preheat cycle must be lengthened in order for proper solder wetting of the pins to occur. Q: Why do the modules sometimes seem to current limit to early? A: Noise on the Parallel Pin, the Input Pins, or the Output Pins can cause premature current limit in the modules. Application Note 13 Paralleling- Current Sharing, Hot Plug-in, and N+M Redundancy and Application Note 18 Board Layout Considerations and Recommendations provide some preventative and corrective measures that can be taken to reduce the noise. Adding the proper bypass caps to these pins will usually solve the problem. Q: Why does the output noise increase when I connect the output return lines of the triple output module together? A: As with most multiple output power supplies, common mode noise can be injected from one output into another causing increased noise. Adding a small, common mode choke of about 25µH per leg to each auxiliary output, before the common ground connection, will prevent this from occurring. See Application Note 14 for more information. Q: How does the output good signal function? A: The output good signal provides an active low output whenever the sensed output voltage is within ±10% of the set output voltage;otherwise it appears as an open collector (Vmax = 40V). The signal is referenced to -SENSE (See Figure 2) and is capable of sinking 15mA typical (8mA minimum). The output low voltage (saturation voltage) is 0.5V or less @ lsink = 1.6mA. The output good signal changes its state in the range Vsense = ±9% to ±11% of Vsetpoint.

Q: How do I use the ON/OFF pin? A: The ON/OFF pin may be used to turn the module off and on remotely using a low level signal. When ON/OFF is pulled low (<1V @4mA, referenced to -Vin), the module is turned off. All that is required to interface the ON/OFF signal to the other circuits is a few external components as shown in Figure 3. Additional ways to use the ON/OFF pin are shown in Application Note 4, Logic On-Off.
