Description
The Bel S7DB-12B 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, low
profile, surface mount DIP package for ease of layout and space savings. 12A 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 5V source is available. Typical applica-
tions include file servers, routers, line cards and other computing and communications equipment.
Applications
• Distributed power architectures
• Data networking equipment
• Telecommunications
• Computers and peripherals
