NON-ISOLATED DC/DC CONVERTERS
12V Input / 0.9V 5.0V Output / 15A
Industry standard pinout
High efficiency means less power dissipation
Remote on/off
Overcurrent protection
Description
The V7PF-15A Series are non-isolated step down DC/DC converters
that operate from a nominal 12V source. These converters are available
in a range of output voltages from 0.9V to 5.0V. They are packaged in an industry standard single-in-line
footprint and provide a maximum 15A output. Standard features include remote on/off, over current protection,
thermal protection, output voltage adjust and remote sense. These products maybe used almost anywhere low-
voltage silicon is being employed and a 12V source is available. Typical applications include file servers,
routers, line cards, and other computing and communications equipment.
