NON-ISOLATED DC/DC CONVERTERS 4.5 – 13.2V Input / 1.0 – 3.3V Output / 6A S7AH-06E / V7AH-06E Series PRELIMINARY • Compact surface mount package • High efficiency means less power dissipation • Remote on/off • Extra wide input voltage range • Ideal for Intermediate Bus Architecture applications 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.

The Trim Down resistor should be connected between the Trim pin and Vout. The Trim Up resistor should be connected between the Trim pin and Ground. Only one of the resistors should be used for any given application.
