Signal Characteristics: Per table on page 5. 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). Output Voltage Adjust: The output voltage of the converter can be adjusted above or below the nominal output voltage as specified in the Output Characteristics Table. 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. V oltage 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. V o is the desired output voltage. For the GPP1V5-15 and GPP1V5-25, the trim voltage for these two units is: 90.5 12.1V TRIM = ——— * V O – —— V olts44.97 6 For the GPP2V2-15 and GPP2V2-25, the trim voltage for these two units is: 11.4935 12.1V TRIM = ———— * V O – —— V olts8.3862 6 For the GPP3V3-15 and GPP3V3-25, the trim voltage for these two units is: 4.067 12.1V TRIM = ——— * V O – —— V olts2.06 3 For the GPP5V0-15 and GPP5V0-20, the trim voltage for these two units is: 1.829 * V o - 6.05V TRIM = ———————— V olts1.238 Resistor Programming: Output voltage may be adjusted down from the nominal output voltage with a resistor connected between the “Trim” pin (pin 4) and the “-Sense” pin (pin 1). For the GPP1V5-15 and GPP1V5-25, the trim resistor, R trim for these two units is: For the GPP2V2-15 and GPP2V2-25, the trim resistor, R trim for these two units is: 169.1217 – 114.935 * VO For the GPP3V3-15 and GPP3V3-25, the trim resistor, R trim for these two units is: 5 2.49 *V o – 8.24 For the GPP5V0-15 and GPP5V0-20, the trim resistor, R trim for these two units is: Output voltage may be adjusted up from the nominal output voltage with a resistor connected between the “Trim” pin (pin 4) and the “+ Sense” pin (pin 2).

For the GPP5V0-15 and GPP5V0-20, the trim resistor, R trim for these two units is: V O – 5 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: 1- η TB ASEPLATE = POUTPUT * —— * R B ASEPLATE -AMBIENT + TAMBIENT η Where: TB ASEPLATE is the temperature of the baseplate. Tambient is the local ambient temperature around the converter η is the efficiency of the converter (see Table on page 5) R baseplate-ambientis 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. Overcurrent Protection: The converter shall survive any overload condition indefinitely including short circuit. 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 V out 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.
