Description
The S/V7AH-06E Series are non-isolated step down DC/DC converters
that operate from with an extra wide input range (4.5V to 13.2V). This allows them to operate from a nominal 5V
or 12V source or from an unregulated source such as a bus converter in an Intermediate Bus Architecture
application. These modules are available in a range of output voltages from 1.0V to 3.3V. They are offered in a
compact ovemolded package rated at 6A. Optional lead-forming provides a vertical mount product for minimal
footprint or a surface mount option for very low profile. Standard features include remote on/off, over current
protection and output voltage adjust. These products maybe used almost anywhere low-voltage silicon is being
employed and a nominal 5 – 12V source is available. Typical applications include file servers, routers, line
cards, and other computing and communications equipment.
