TPS61032 概述

The TPS61032 devices provide a power supply solution for products powered by either a one-cell Li-Ion or Li-polymer, or a two to three-cell alkaline, NiCd or NiMH battery. The TPS61032 generates a stable output voltage that is fixed internally on the chip. The TPS61032 provides high efficient power conversion and is capable of delivering output currents up to 1 A at 5 V at a supply voltage down to 1.8 V.

The TPS61032 can be disabled to minimize battery drain. During shutdown, the load is completely disconnected from the battery.

The TPS61032 is packaged in a 16-pin QFN package measuring 4 mm x 4 mm (RSA) or in a 16-pin TSSOP PowerPAD™ package (PWP).
