Output Trim Equations
Equations for calculating the trim resistor (in k) 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 Vo1. The Trim Up resistor should be connected between the Trim pin and COM. Only one of the resistors
should be used for any given application.
