Description
The Bel VRPB-10C modules are a series of non-isolated, step down DC/DC power converters that operate from a nominal
3.3V source. These converters are available in a range of output voltages from 0.9V to 2.5V. 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). The output is closely regulated and the efficiency is typically 95% @
2.5V output at full load. These products may be used almost anywhere low voltage silicon is employed and a 3.3V source is
available. Typical applications include file servers, routers, line cards and other computing and communications equipment.
