DataSheet 30W, Single 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 the 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 lowest impedance.

PAGE 37
DataSheet 30W, Single Output Output voltage set point adjustment allows the user to increase or decrease the output voltage set point of a converter. This is accomplished by connecting an external resistor between the TRIM pin and either the Vo (+) or Vo (-) pins. With an external resistor between the TRIM and Vo (-) pin, the output voltage set point increases. With an external resistor between the TRIM and Vo (+) pin, the output voltage set point decreases.

DataSheet 30W, Single Output Remote ON/OFF Control Positive Logic – (no suffix) , the positive logic remote ON/OFF control circuit is included. Ex.: PXD30-24WS05 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.
