| 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. Output Current 10A 10A 10A Max.
