DESCRIPTION
The TPS62000 device is a low-noise synchronous step-down dc-dc converter that is 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 TPS62000
operates typically down to an input voltage of 1.8 V, with a specified minimum input voltage of 2 V.
