Description
The Bel VRPB-10B modules are a series of non-isolated, step down DC/DC power converters that operate from a nominal 5V
source. These converters are available in a range of output voltages from 0.9V to 3.3V. They are packaged in a compact, SIP
package rated at 10A. Standard features include remote on/off, over current and short circuit protection, output voltage adjust
and industrial temperature range (-40° to +85° C). ThDe aotuatpSuhteisect4loUs.eclyomregulated and the efficiency is typically 95.5% @ 3.3V
output at full load. These products may be used almost anywhere low voltage silicon is employed and a 5V source is available.
Typical applications include file servers, routers, line cards and other computing and communications equipment.
