Highly inductive source impedance can affect the stability of the power module. For the test configuration in Figure 7, a 470μF Low ESR aluminum capacitor, CIN , mounted close to the power module helps ensure the stability of the unit. Consult the factory for further application guidelines. Output Capacitance Note: Measure the input reflected-ripple current with a simulated source inductance (LTEST) of 12 µH. Capacitor CS offsets possible battery impedance. Measure the current, as shown above. Figure 7. Input Reflected Ripple Current Test Setup. The FNW700R power module requires a minimum output capacitance of 470µF Low ESR aluminum capacitor, Cout to ensure stable operation over the full range of load and line conditions, see Figure 8. If the O ambient temperature is under -20 C, it is required to use at least 3 of the minimum capacitors in parallel. In general, the process of determining the acceptable values of output capacitance and ESR is complex and is load-dependant. Safety Considerations Note: Use a Cout (470 µF Low ESR aluminum or tantalum capacitor typical), a 0.1 µF ceramic capacitor and a 10 µF ceramic capacitor, and Scope measurement should be made using a BNC socket. Position the load between 51 mm and 76 mm (2 in. and 3 in.) from the module. Figure 8. Output Ripple and Noise Test Setup. Note: All measurements are taken at the module terminals. When socketing, place Kelvin connections at module terminals to avoid measurement errors due to socket contact resistance. Figure 9. Output Voltage and Efficiency Test Setup. LINEAGE POWER For safety-agency approval of the system in which the power module is used, the power module must be installed in compliance with the spacing and separation requirements of the end-use safety agency standard, i.e., UL60950-1, CSA C22.2 No. 60950-1-03, EN60950-1 and VDE 0805:2001-12. For end products connected to –48Vdc, or –60Vdc nominal DC MAINS (i.e. central office dc battery plant), no further fault testing is required. *Note: -60Vdc nominal battery plants are not available in the U.S. or Canada. For all input voltages, other than DC MAINS, where the input voltage is less than 60Vdc, if the input meets all of the requirements for SELV, then: The output may be considered SELV. Output voltages will remain within SELV limits even with internally-generated non-SELV voltages. Single component failure and fault tests were performed in the power converters. One pole of the input and one pole of the output are to be grounded, or both circuits are to be kept floating, to maintain the output voltage to ground voltage within ELV or SELV limits. However, SELV will not be maintained if VI(+) and VO(+) are grounded simultaneously. 6 Data Sheet September 6, 2008 FNW700R Power Modules; DC-DC Converters 36 – 75 Vdc Input; 28Vdc Output; 700W Output Safety Considerations (continued) For all input sources, other than DC MAINS, where the input voltage is between 60 and 75Vdc (Classified as TNV-2 in Europe), the following must be meet, if the converter’s output is to be evaluated for SELV: The input source is to be provided with reinforced insulation from any hazardous voltage, including the ac mains. One VI pin and one Vo pin are to be reliably earthed, or both the input and output pins are to be kept floating. Another SELV reliability test is conducted on the whole system, as required by the safety agencies, on the combination of supply source and the subject module to verify that under a single fault, hazardous voltages do not appear at the module’s output. Figure 10. Circuit configuration for using Remote On/Off Implementation. Overcurrent Protection Feature Description To provide protection in a fault output overload condition, the module is equipped with internal currentlimiting circuitry and can endure current limit for few milli-seconds. A latching shutdown option is standard. If overcurrent persists for few milli-seconds, the module will shut down and remain off until the module is reset by either cycling the input power or by toggling the on/off pin for one second. An auto-restart option (4) is also available in a case where an auto recovery is required. If overcurrent persists for few milli-seconds, the module will shut down and auto restart until the fault condition is corrected. If the output overload condition still exists when the module restarts, it will shut down again. This operation will continue indefinitely, until the overcurrent condition is corrected. Remote On/Off Over Voltage Protection Remote ON/OFF control is available as standard and has positive logic remote On/Off mode only. The converter will be active as long as a current Ion/off (1 to 5mA) is flowing into the ON/OFF+ (pin 4) and from the ON/OFF- (pin 3), and inactive when no current is flowing. Remote control pins are isolated up to 1.5 kV. The voltage to drive this current can be derived from the input voltage, the output voltage, or an external supply with an appropriate current limit resistor. The maximum forward current allowable without damage is 5 mA, and the maximum reverse current is 10mA. A typical remote ON/OFF circuit is shown as Figure 10. The current limit resistor (R1) is connected from Vin (+) pin to ON/OFF + pin, an open collector or an equivalent switch can be connected between ON/OFF - and VI (-) pins to control ON/OFF operation. A 0 Ohm resistor (R2) can be used if no open collector or switch used. For 48Vin, an appropriate R1 value is recommended to be 30Kohm (0.5W). The output overvoltage protection consists of circuitry that monitors the voltage on the output terminals. If the voltage on the output terminals exceeds the over voltage protection threshold, then the module will shutdown and latch off. The overvoltage latch is reset by either cycling the input power for one second or by toggling the on/off signal for one second. The protection mechanism is such that the unit can continue in this condition until the fault is cleared. An auto-restart option (4) is also available in a case where an auto recovery is required. All flammable materials used in the manufacturing of these modules are rated 94V-0, or tested to the UL60950 A.2 for reduced thickness. The input to these units is to be provided with a maximum 30 A fast-acting fuse in the unearthed lead. LINEAGE POWER Output Voltage Programming Trimming allows the user to increase or decrease the output voltage set point of a module. Trimming down is accomplished by connecting an external resistor between the TRIM pin and the SENSE(-) pin. Trimming up is accomplished by connecting external resistor between the SENSE(+) pin and Vo(+) pin. The trim resistor should be positioned close to the module. Be sure to use a zero resistor or short SENSE(+) and Vo(+) pins when the trim up function is not used. If not using the trim down feature, leave the TRIM pin open. 7 Data Sheet September 6, 2008 FNW700R Power Modules; DC-DC Converters 36 – 75 Vdc Input; 28Vdc Output; 700W Output Feature Description (continued) With an external resistor between the TRIM and SENSE(-) pins (Radj-down), the output voltage set point (Vo,adj) decreases (see Figure 11). The following equation determines the required external-resistor value to obtain a percentage output voltage change of Δ%. For output voltages: 28V ⎛ 100 ⎞ Radj − down = 5.97 × ⎜ − 1⎟KΩ ⎝ Δ% ⎠ Where, Δ% = Vo, nom − Vdesired × 100 Vo, nom Vdesired = Desired output voltage set point (V). Figure 11. Circuit Configuration to Decrease Output Voltage. Trim Up – Increase Output Voltage With an external resistor connected between the Vo(+) and SENSE(+) pins (Radj-up), the output voltage set point (Vo,adj) increases (see Figure 12). The following equation determines the required external-resistor value to obtain a percentage output voltage change of Δ%. For output voltages: 28V Radj − up = Vo, nom × Δ % KΩ 100 Figure 12. Circuit Configuration to Increase Output Voltage. The voltage between the Vo(+) and Vo(-) terminals must not exceed the minimum output overvoltage shut-down value indicated in the Feature Specifications table. This limit includes any increase in voltage due to remotesense compensation and output voltage set-point adjustment (trim). See Figure 13. Although the output voltage can be increased by both the remote sense and by the trim, the maximum increase for the output voltage is not the sum of both. The maximum increase is the larger of either the remote sense or the trim. The amount of power delivered by the module is defined as the voltage at the output terminals multiplied by the output current. When using remote sense and trim, the output voltage of the module can be increased, which the same output current would increase the power output of the module. Care should be taken to ensure that the maximum output power of the module remains at or below the maximum rated power. Examples: To trim down the output of a nominal 28V module to 16.8V Δ% = 28V − 16.8V × 100 28V ∆% = 40 ⎛ 100 ⎞ Radj − down = 5.97 × ⎜ − 1⎟KΩ ⎝ 40 ⎠ Radj-down = 8.96 kΩ Where, To trim up the output of a nominal 28V module to 30.8V Vdesired − Vo, nom Δ% = × 100 Vo, nom Δ% = Vdesired = Desired output voltage set point (V). Δ% = 10 30.8V − 28V × 100 28V R adj− up = 28 × 10 KΩ 100 Radj-up = 2.8 KΩ LINEAGE POWER 8 Data Sheet September 6, 2008 FNW700R Power Modules; DC-DC Converters 36 – 75 Vdc Input; 28Vdc Output; 700W Output Feature Description (continued) Remote sense Remote sense minimizes the effects of distribution losses by regulating the voltage at the remote-sense connections (see Figure 13). For No Trim or Trim down application, the voltage between the remote-sense pins and the output terminals must not exceed the output voltage sense range given in the Feature Specifications table i.e.: [Vo(+) – Vo(-)] – [SENSE(+) – SENSE(-)] ≤ 2% of Vo,nom. The voltage between the Vo(+) and Vo(-) terminals must not exceed the minimum output overvoltage shutdown value indicated in the Feature Specifications table. This limit includes any increase in voltage due to remote-sense compensation and output voltage setpoint adjustment (trim). See Figure 13. If not using the remote-sense feature to regulate the output at the point of load, then connect SENSE(+) to Vo(+) and SENSE() to Vo(-) at the module. Although the output voltage can be increased by both the remote sense and by the trim, the maximum increase for the output voltage is not the sum of both. The maximum increase is the larger of either the remote sense or the trim. The amount of power delivered by the module is defined as the voltage at the output terminals multiplied by the output current. When using remote sense and trim: the output voltage of the module can be increased, which at the same output current would increase the power output of the module. Care should be taken to ensure that the maximum output power of the module remains at or below the maximum rated power. The module can be restarted by cycling the dc input power for at least one second or by toggling the remote on/off signal for at least one second. Auxiliary Power Output The module has an auxiliary power output, available on pin 16, referenced to the Sense- pin. The output is derived from the internal secondary bias supply and is capable of delivering up to 15 mA, with a voltage range that varies between 9Vdc and 13 Vdc. This supply is typically used to drive LEDs. To prevent internal module damage, do not connect or short this pin to any other pin on the module. Power Good Signal The module contains a power good signal on pin 15, consisting of an open collector circuit that is referenced to the Sense- pin on the secondary side of the module. The power good signal is active low, when the module is operating normally. The maximum current that can sunk at this pin, during normal operation active low, is 35 mAdc, and the maximum voltage allowed on the pin, during module abnormal operation active high, is 35Vdc. During transient load changes or during overcurrent hiccup events, the sanity of the power good signal is not guaranteed. Figure 13. Effective Circuit Configuration for SingleModule Remote-Sense Operation Output Voltage. Over Temperature Protection The FNW700R module provides with non-latching over temperature protection. A temperature sensor monitors the operating temperature of the converter. If the reference temperature exceeds a threshold of 106 °C (typical) at the center of the baseplate, the converter will shut down and disable the output. When the baseplate temperature has decreased by approximately 20 ºC the converter will automatically restart. LINEAGE POWER 9 FNW700R Power Modules; DC-DC Converters 36 – 75 Vdc Input; 28Vdc Output; 700W Output Data Sheet September 6, 2008 Thermal Considerations The power modules operate in a variety of thermal environments; however, sufficient cooling should be provided to help ensure reliable operation of the unit. Heat-dissipating components inside the unit are thermally coupled to the case. Heat is removed by conduction, convection, and radiation to the surrounding environment. Proper cooling can be verified by measuring the case temperature. Peak temperature (TC) occurs at the position indicated in Figure 14. Considerations include ambient temperature, airflow, module power dissipation, and the need for increased reliability. A reduction in the operating temperature of the module will result in an increase in reliability. The thermal data presented here is based on physical measurements taken in a wind tunnel. For reliable operation this temperature should not exceed 100ºC. O U T P U T C U R R E N T , I o (A ) 30 25 20 15 10 5 0 20 30 40 50 60 70 80 90 100 CASE TEMERATURE, TC, (oC) Figure 15.

Case (Tc ) Temperature Measurement Location (top view). The output power of the module should not exceed the rated power for the module as listed in the ordering Information table. Although the maximum TC temperature of the power modules is 100 °C, you can limit this temperature to a lower value for extremely high reliability. Please refer to the Application Note “Thermal Characterization Process For Open-Frame BoardMounted Power Modules” for a detailed discussion of thermal aspects including maximum device temperatures. Thermal Derating Thermal derating is presented for two different applications: 1) coupled to a cold plate inside a sealed clamshell chassis, without any internal air circulation, and 2) traditional open chassis or cards with force air flow. In application 1, the module is cooled entirely by conduction of heat from the module primarily through the top surface to a coldplate, with some conduction through the module’s pins to the power layers in the system board; for application 2; the module is cooled by heat removal into a forced airflow that passes through the interior of the module and over the top baseplate and/or an attached heatsink.

Avoid placing copper areas on the outer layer directly underneath the power module. Post Solder Cleaning and Drying Considerations Post solder cleaning is usually the final circuit-board assembly process prior to electrical board testing. The result of inadequate cleaning and drying can affect both the reliability of a power module and the testability of the finished circuit-board assembly.
