NON-ISOLATED DC/DC CONVERTERS
3.0 Vdc - 5.5 Vdc Input
1.0 Vdc - 3.3 Vdc/12 A Output
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 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.
