Description
The Bel S7DB-10E modules are a series of non-isolated, step down DC/DC power converters that operate from a nominal
4.5V to 13.2V source. These converters are available in a range of output voltages from 1.0V to 5.0V. The output is closely
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.
Applications
• Distributed power architectures
• Data networking equipment
• Telecommunications
• Computers and peripherals
