Description
The Bel xRAH-05Exx0 is part of the low cost non-isolated dc/dc converter Power Module series. The modules
use a SMD or SIP package for ease of layout and space savings. The output is closely regulated and the
efficiency of 3.3 Vdc output module is typically 91% at full load.

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.

RoHS Compliance
Complies with the European Directive 2002/95/EC, calling for the elimination of lead and
other hazardous substances from electronic products. These parts are not however
compatible with the higher temperatures associated with lead free solder processes and
must be soldered using a reflow profile with a peak temperature of no more than 240 ºC.
