Description
The Bel V7PD-15B 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 1.2V to 3.3V. They are packaged in an industry
standard, single-in-line footprint and provide a maximum 15A output. Standard features include remote on/off, over current
and short circuit protection, output voltage adjust and remote sense. 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.
