Description

The Bel S7DB-07A modules are a series of non-isolated, step down DC/DC power converters that operate from a nominal

12V source. These converters are available in a range of output voltages from 1.2V to 5.0V. They are packaged in a compact,

low profile, surface mount DIP package for ease of layout and space savings. 7A maximum output is also provided. Standard

features include remote on/off, 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 12V source is available. Typical applications include file

servers, routers, line cards and other computing and communications equipment.
