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.

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.
