Description
The Bel xRAH-01CXx0 is part of the low cost non-isolated dc/dc converter series. The modules use a SMD or
SIP package or vertical package for ease of layout and space savings. The output is closely regulated and the
efficiency of 12 Vdc output module is typically 86% at full load. Typical features include allows burst mode
operation at low load currents and trim function (option).

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.

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.
