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.

Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas

Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.

PRODUCTION DATA information is current as of publication date.

Products conform to specifications per the terms of the Texas

Instruments standard warranty. Production processing does not

necessarily include testing of all parameters.
