DataSheet 40W, Single Output Output Over Voltage Protection The output over-voltage protection consists of an output Zener diode that monitors the voltage on the output terminals. If the voltage on the output terminals exceeds the over-voltage protection threshold, then the Zener diode clamps the output voltage. Short Circuitry Protection Continuous, hiccup and auto-recovery mode. During a short circuit the converter shuts down. The average current during this condition will be very low .

DataSheet 40W, Single Output Heat Sink Consideration All dimensions in millimeters Use heat-sink (7G-0026A) for lowering temperature and higher reliability of the module.
PAGE 54
DataSheet 40W, Single Output Remote ON/OFF Control The Remote ON/OFF Pin is used to turn on and off the DC-DC converter. The user must use a switch to control the logic voltage (high or low level) of the ON/OFF pin ,referenced to Vi (-). The switch can be open collector transistor, FET, or Opto-Coupler that is capable of sinking up to 0.5 mA at a low-level logic Voltage. For High-level logic of the ON/OFF signal (maximum voltage): the allowable leakage current of the switch at 12V is 0.5 mA.

DataSheet 40W, Single Output Output Voltage Adjustment Output voltage set point adjustment allows the user to increase or decrease the output voltage set point of a module. This is accomplished by connecting an external resistor between the TRIM pin and either the SENSE(+) or SENSE(-) pins. With an external resistor between the TRIM and SENSE(-) pin, the output voltage set point increases. With an external resistor between the TRIM and SENSE(+) pin, the output voltage set point decreases.

DataSheet 40W, Single Output Remote Sense Application Circuit The Remote Sense function can regulate the voltage at the terminals (local sensing) or at the load. (remote sensing). The maximum voltage compensation is 10% Vo, i.e.: [Vo (+) to Vo (-)] – [Sense (+) to Sense (-)] < 10% Vo If the Remote Sense function is not used, then the SENSE (+) should be connected to OUTPUT (+) and the SENSE (-) should be connected to OUTPUT(-) of the PXF module.

DataSheet 40W, Single Output Safety and Installation Instruction Fusing Consideration Caution: This converter is not internally fused. An input line fuse must always be used. This encapsulated converter can be used in a wide variety of applications, ranging from simple stand-alone operation to an integrated part of a sophisticated power architecture. For maximum flexibility, internal fusing is not included; however, to achieve maximum safety and system protection, always use an input line fuse.
