Description
The Bel V7PA-03A 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 a single-in-line
footprint and provide a maximum 3A output. Standard features include remote on/off, over current protection and output
voltage adjust. 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.
