3 Description

The TPS6200x devices are a family of low-noise

synchronous step-down DC/DC converters that are

ideally suited for systems powered from a 1-cell Li-ion

battery or from a 2- to 3-cell NiCd, NiMH, or alkaline battery. The TPS6200x operates typically down to an

input voltage of 1.8 V, with a specified minimum input

voltage of 2 V.

The TPS62000 operates over a free-air temperature

range of –40°C to 85°C.The device is available in the

10-pin (DGS) microsmall outline package (VSSOP).
