Description
The Bel SRDB-10E modules are a series of non-isolated, step down DC/DC power converters that operate from a nominal regulated and the efficiency of the 3.3V output module is typically 88% at full load. The modules are packaged in a compact, low profile, surface mount DIP package for ease of layout and space savings. 10A maximum output is also provided. Standard features include remote on/off, remote sense, over current and short circuit protection, UVLO and output voltage adjust. These products may be used almost anywhere low voltage silicon is employed and a 4.5V to 13.2V source is available. Typical applications include file servers, routers, line cards and other computing and communications equipment.
