Output Trim Equations
Equations for calculating the trim resistor given the desired adjusted voltage (Vadj) and the nominal output voltage
of the converter (Vo) are shown below. 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.
