Description
The Bel xRAH-06Exx0 is part of the low cost non-isolated dc/dc converter series. The modules use a surface
mount package or vertical package for ease of layout and space savings, with a low profile of only 7.82 mm. The
output is closely regulated and the efficiency of 3.3 Vdc output module is typically 91% at full load. Typical
features include Remote On/Off, under-voltage lockout, over-current protection and short circuit protection.

Output Trim Equations
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.
