NON-ISOLATED DC/DC CONVERTERS 2.5V Input / 1.0 – 1.5V Output / 10A S7AH-10J / V7AH-10J Series • • • • • Compact surface mount package Excellent thermal performance PRELIMINARY High efficiency means less power dissipation Remote on/off Low cost Description The S/V7AH-10J Series are non-isolated step down DC/DC converters that operate from a nominal 2.5V source. These converters are available in a range of output voltages from 1.0V to 2.5V. They are offered in a compact ovemolded package rated at 10A. 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 2.5V source is available. Typical applications include file servers, routers, line cards, and other computing and communications equipment. Part Selection Output Voltage 1.5V 1.2V 1.0V Input Voltage 2.5V 2.5V 2.5V Max.
