TPS62000-HT
Overview
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. 1 Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas Instruments semiconductor products and disclaimers thereto.
