| NON-ISOLATED DC/DC CONVERTERS 12V Input / 0.9V - 5.0V Output / 15A V7PF-15A Series * * * * PRELIMINARY 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 lowvoltage silicon is being employed and a 12V source is available. Typical applications include file servers, routers, line cards, and other computing and communications equipment. Part Selection Output Voltage 0.9 - 5.0V 1.2 - 5.0V Input Voltage 12V 12V Max. Output Current 15A 15A Max. Output Power 75W 75W Typical Eff.
