DataSheet 30W, Dual Output Input Source Impedance The converter should be connected to a low impedance input source. Highly inductive source impedance can affect the stability of the converter. Input external L-C filter is recommended to minimize input reflected ripple current. The inductor has a simulated source impedance of 12μH and capacitor is Nippon chemi-con KY series 47μF/100V. The capacitor must be located as close as possible to the input terminals of the converter for lower impedance.
PAGE 21
DataSheet 30W, Dual Output 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 shown in the figure below. The temperature at this location should not exceed 105°C. When operating, adequate cooling must be provided to maintain the test point temperature at or below 105°C .

DataSheet 30W, Dual Output Remote ON/OFF Control Positive Logic – (no suffix) , the positive logic remote ON/OFF control circuit is included. Ex.: PXD30-24WD05 Turns the converter ON during logic High on the On/Off pin and turns the converter OFF during logic Low. The On/Off pin is an open collector/drain logic input signal (Von/off) that is referenced to GND. If not using the remote on/off feature, an open circuit between on/off pin and (–) input pin is needed to turn the module on.

DataSheet 30W, Dual Output Safety and Installation Instructions 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.
