Description
The Bel SRAH-05B and VRAH-05B 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 a compact, overmolded package rated at 5A. Optional lead forming provides a vertical mount product for minimal footprint
or a surface mount option for a very low profile. Standard features include remote on/off, over current and short circuit
protection, and output voltage adjust. 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
• Distributed power architectures
• Data networking equipment
• Telecommunications
• Computers and peripherals
