TPS61322 Datasheet 1.8-a Switch Current Boost Converter

Manufacturer: Texas Instruments

Overview: TPS61322 SLVSDY5E – JANUARY 2018 – REVISED FEBRUARY 2024 TPS61322 6.5-µA Quiescent current, 1.

General Description

The TPS61322 is a synchronous boost converter with only 6.5-µA quiescent current.

The TPS61322 provides a power-supply solution for products powered by alkaline battery, NiMH rechargeable battery, or one-cell Li-ion battery.

The boost converter is based on a hysteretic control topology using synchronous rectification to obtain maximum efficiency at minimal quiescent current.
