Signal Characteristics: Per table on page 5. Input Signals: 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). Enable_L does not require an external pull-up resistor. If an external pull-up is used it should be tied to +5V . To minimize start-up problems it is recommended that Enable_L be driven from an open-drain configured FET. V oltage Adjust: The output voltage of the converter shall be adjustable as specified in the table on page 3. The voltage adjust pin sources 1 mA current. The adjustment shall be done using an external voltage source or a resistor connected between the V oltage Adjust pin and the – Sense pin. See below for output voltage adjustment application information. Current Share: When two or more converters are connected in parallel, their current share pins must be connected together to allow proper load sharing. Sync: When two or more converters from the same manufacturer are connected in parallel, their sync pins may be connected together to synchronize their operating frequencies. When two or more converters from different manufacturers are connected in parallel their sync pins must NOT be connected together. Output Signals: MODOK_L: MODOK_L shall be asserted to indicate that the output voltage is in regulation. When two or more converters are operating in parallel a failed converter may or may not de-assert its MODOK_L signal. OTW _L: OTW_L shall be asserted to indicate that the converter temperature is too high and that the converter is about to shut down. OTW_L will be asserted a minimum of 500 msec before the converter shuts down due to an overtemperature condition. The output of this signal is the open drain of a FET. The output is current limited to 8-15 mA and may be used to drive an external LED directly. Output Voltage Adjustment: V oltage Programming: A voltage may be applied between the V oltage Adjust pin (pin 5) and the – Sense pin (pin 1) to adjust the output voltage up or down from the nominal output voltage by a maximum of ±10%. The trim voltage for the GPH1V5-40 and GPH1V5-60 is: For the GPH2V2-40 and GPH2V2-60 the output voltage may be trimmed to +15% , - 10%. The trim voltage for these two units is: The trim voltage for the GPH3V3-40 and GPH3V3-60 is: The trim voltage for the GPH5V0-30 and GPH5V0-40 is: Resistor Programming: A resistor may be connected between the V oltage Adjust pin (pin 5) and the – SENSE pin (pin 1) to adjust the output voltage up or down from the nominal output voltage by a maximum of +/- 10 %. The GPH2V2-40, -60 may be adjusted +15 %, -10 %. The value of the trim resistor is for a single converter or for multiple paralleled converters with separate trim resistors on each of their V oltage Adjust pins. Although not recommended, the V oltage Adjust pins for N paralleled converters may be tied together. In this case the value of the trim resistor will be R TRIM /N. For the GPH1V5-40 and GPH1V5-60, the trim resistor value in Kohms for these two units is: The resistor value in Kohms for the GPH2V2-40 and GPH2V2-60 is: The resistor value in Kohms for the GPH3V3-40 and GPH3V3-60 is:

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 – ηTB 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 R B ASEPLATE -AMBIENT is the thermal resistance from the baseplate to the ambient environment. This is a function of the heat sink and air velocity. See table on page 5 for thermal resistance characteristics. 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. Application Notes Paralleling Converters: Tw o to five converters can be paralleled as long as the following conditions are met. When all of the converters are from the same manufacturer the current share pins must be connected together and the sync pins may be connected together if desired. When converters from different manufacturers are paralleled, the current share pins must be connected together and the sync pins must NOT be connected together. The maximum output current for paralleled configurations is shown in the table on page 5. When a converter fails in a parallel configuration it may or may not deassert its MODOK_L signal. It should also be noted that current for the control circuit in the converter flows through the – SENSE lead. For this reason it is important to keep the impedance between the – SENSE pins on the converters in a parallel configuration low. The best approach is to connect the – SENSE pins together with as large of an etch as possible (250 milliohms maximum recommended) and then run a single set of sense leads to the remote sense point at the load.
