Description
The Bel SRAH-02C and VRAH-02C modules are non-isolated, step up DC/DC power converters that operate from a nominal
3.3V source with an output voltage of 5V. They are packaged in a compact, overmolded package rated at 1.5A. Optional lead
forming provides a vertical mount product for minimal footprint or a surface mount option for a very low profile. Standard
features include output voltage adjust and industrial temperature range (-40° to +85° C). The output is closely regulated and
the efficiency is typically 87% at full load. These products may be used almost anywhere low voltage silicon is employed and a
3.3V source is available. Typical applications include file servers, routers, line cards and other computing and communications
equipment.
*Optional Burst/skip mode operating at light load or no load.
