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.
Applications
* * * Telecommunications Networking Computers and peripherals
Options
* * Remote sense Industrial temperature range
