The Bel xRBH-03Hxx0 is a part of the low cost non-isolated DC/DC
power converter series providing up to 3 A output current. Optional
lead forming provides a vertical mount product for minimal footprint or
a surface mount option for a very low profile. The output is closely
regulated and the efficiency of 3.3 VDC output is typically 88% at full
load. Typical features include remote on/off, input under voltage
lockout, over current protection and short circuit protection.

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.
