DataSheet 60W, Single Output Thermal Consideration The converter operates in a variety of thermal environments. Sufficient cooling should be provided to help ensure reliable operation of the unit. Heat is removed by conduction, convection, and radiation to the surrounding environment. Proper cooling can be verified by measuring the point as the figure below. The temperature at this location should not exceed 110°C.

DataSheet 60W, 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 an open collector transistor, FET or Photo-Coupler that is capable of sinking up to 1 mA at low-level logic voltage. At High-level logic(ON/OFF signal maximum voltage): the allowable leakage current of the switch at 12V is 0.5 mA.

DataSheet 60W, 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 60W, Single Output Remote Sense Application Circuit The Remote Sense function can be used to regulate the voltage at the load. The Remote Sense voltage range can’t be greater than 10% Vo, i.e.: [Vo (+) to Vo (-)] – [Sense (+) to Sense (-)] ≦ 10% Vo If the Remote Sense function is not used,, connect the SENSE (+) to OUTPUT (+) and connect the SENSE (-) to OUTPUT(-) of the PXF60 converter.

DataSheet 60W, Single Output Safety and Installation Instruction Fusing Consideration Caution: This converter is not internally fused. An input line fuse must always be used. This 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.
