Description
The Bel xRAH-10Jxx0 is part of the low cost non-isolated dc/dc power converter 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 1.5
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.

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.
