Control Specifications Parameter Min Typ Max Notes Remote On/Off Signal Low (Unit Off) 0 V - 0.5 V Signal High (Unit On) 2 V - 5.5 V Remote on/off pin open, the module is on. Output Trim Equations Equations for calculating the trim resistor (in kΩ) given the desired adjusted voltage (Vadj) and the nominal output voltage of the converter (Vnom) are shown below. The Trim Down resistor should be connected between the Trim pin and Vout. The Trim Up resistor should be connected between the Trim pin and Ground. Only one of the resistors should be used for any given application.
