Output Trim Equations
Equations for calculating the trim resistor given the desired adjusted voltage (Vadj) and the nominal output
voltage of the converter (Vnom) are shown below. The Trimup resistor should be connected between the Trim pin
and Ground and the Trimdown resistor should be connected between the Trim pin and Vout pin.
