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).
