Description
The Bel VRPC-10A series modules are non-isolated, step down DC/DC power converters that operate from a nominal 12V
source. These converters are available in a range of output voltages from 1.5V to 3.3V. They are packaged in an industry
standard single-in-line footprint and provide a maximum 10A output. Standard features include remote on/off, over current
protection and output voltage adjust. Remote sense is an optional feature. These products may be used almost anywhere
low-voltage silicon is employed and a 12V source is available. Typical applications include file servers, routers, line cards
and other computing and communications equipment.

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 240ºC.
