TPS62000-HT - Texas Instruments

TPS62000-HT HIGH-EFFICIENCY STEP-DOWN LOW POWER DC-DC CONVERTER

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 c.
