Input Signals: Enable_L: This unit has both primary and secondary output enable: Primary Enable_L: This input signal is used to enable the output of the converter when activated (active Low). The signal is referenced to the input side (-Vin pin 11). Secondary Enable_L: This input signal is used to enable the output of the converter when activated (active Low). The signal is referenced to the output side (-Sense).

The range of adjustment above the nominal output voltage is limited by the internal overvoltage trip point settings. The overvoltage trip point settings do not change with output voltage adjustments. Output Voltage Turn On Time: The external circuit used to turn on the converter's "enable circuit" is per the Figure on page 5. Voltage Programming: A voltage may be applied between the “Trim” pin (pin 4) and the “– Sense“ pin (pin 1) to adjust the output voltage up or down from the nominal output. Vo is the desired output voltage.

The values of current limit and short circuit shall be per the Output Characteristics Table. Overvoltage Protection: The converter shall be protected against any overvoltage across Vout pins by shutting down the output at the values specified in the Output Characterisitics Table. This is a latched condition and either the input voltage has to be recycled or the primary enable signal (P_ENABLE_L) has to be recycled to reset normal operation. Recommended Input Filter, Fuse and Case Connections: A fuse is required in series with the plus or minus side of the 48V input to meet safety requirements. The following input filter circuit is recommended for all applications. The fuse should be inserted between the capacitors and the plus or minus input of the converter. The case should be connected to the output return. L1 Thermal Considerations: Thermal considerations are an important factor in the reliable operation of the converter. The maximum operating baseplate temperature is 100°C. The maximum recommended operating baseplate temperature is 90°C. The baseplate temperature is a function of the losses within the converter, the converter ambient temperature, and airflow across the heat sink. The reference baseplate temperature is measured at the center coordinates of the baseplate. The baseplate temperature can be approximated by the following equation: TBASEPLATE = POUTPUT * —— * RBASEPLATE-AMBIENT + TAMBIENT 1- η η Where: TBASEPLATE Tambient η 48V 2 1 ° C1 270µF 63V + C2 1µF 100V In (+) is the temperature of the baseplate. is the local ambient temperature around the converter is the efficiency of the converter (see Table on page 5) 48V RTN 4 80 F1 UH ° 3 In (–) In (+) In (–) Rbaseplate-ambient is the thermal resistance from the baseplate to the ambient environment. This is a function of the heat sink and air velocity. Thermal Shutdown: The converter shall shutdown under a thermal overload. This is a latched condition and either the input voltage has to be recycled or the primary enable signal (P_ENABLE_L) has to be recycled to reset normal operation. + Input – P Enable DC/DC Converter + Output RLOAD C3 1µF 100V C4 1µF 100V Case – L1 Common Mode Inductor C1 270µF, 63V Aluminum Electrolytic Capacitor C2-C4 1µF, 100V Ceramic capacitor Polaris Series, Page 7 WWW.GALAXYPWR.COM Part No. 99–003 Rev. 1.0 PACKAGE DETAIL Pin Assignments Heatsink Profile .500±.010 Pin No. Designation Pin Size (inch) Tolerance (inch) .240 .200 .040 pins 4plcs .150 1.300 .900 .450 .300 MAX .225 .200 Side View 2.400 ±.010 .200 .100 9 10 11 12 7 1 2 8 1 2 3 4 5 6 7 8 9 10 11 12 .100 .025 sq pin .100 grid, 6 plcs .025 .175 .060 pins 2plcs 5 6 .150 .400 .250 M3X 0.5 4plcs 2.050 2.100 -Sense +Sense S_Enable_L (Secondary Enable) Trim NC NC -Vout +Vout Case P_Enable_L (Primary Enable) -Vin +Vin 0.025 Sq 0.025 Sq 0.025 Sq 0.025 Sq 0.025 Sq 0.025 Sq 0.060 0.060 0.040 0.040 0.040 0.040 ±0.001 ±0.001 ±0.001 ±0.001 ±0.001 ±0.001 ±0.002 ±0.002 ±0.002 ±0.002 ±0.002 ±0.002 Bottom View ORDERING INFORMATION Model Number Output Voltage Max Current Efficiency (Typ) Model Number Output Voltage Max Current Efficiency (Typ) GPP5V0-20 GPP5V0-15 GPP3V3-25 GPP3V3-15 5.0V 5.0V 3.3V 3.3V 20 A 15 A 25 A 15 A 84% 85% 80% 82% GPP2V2-25 GPP2V2-15 GPP1V5-25 GPP1V5-15 2.2V 2.2V 1.5V 1.5V 25 A 15 A 25 A 15 A 73% 75% 70% 71% * Heatsinks required: available on request.
