Texas Instruments TPS61021A

Description

The TPS61021A provides a power supply solution forportable or smart devices powered by alkaline, NiMH,Li-Mn, or Li-ion batteries. The TPS61021A is capableof outputting 3.3-V voltage and 1.5-A current from abattery discharged to as low as 1.8 V. Capable ofoperating with 0.5-V input voltage enables theTPS61021A to extend the battery run time.
