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.
