Description
The Bel VRPB-06B series modules are 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 1.5V to 3.3V. They are packaged in an industry
standard single-in-line footprint and provide a maximum 6A output. Standard features include remote on/off, over current
protection and output voltage adjust. Optional features include remote sense and industrial temperature range. 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.
