TPS61099 Datasheet Synchronous Boost Converter

Manufacturer: Texas Instruments

Overview: TPS61099 SLVSD88L – JULY 2016 – REVISED AUGUST 2021 TPS61099x Synchronous Boost Converter with Ultra-Low Quiescent Current.

General Description

The TPS61099x device is a synchronous boost converter with 1-µA ultra-low quiescent current.

The device is designed for products powered by an alkaline battery, NiMH rechargeable battery, Li-Mn battery, or rechargeable Li-Ion battery where high efficiency under light-load condition is critical to achieve long battery life operation.

The TPS61099x boost converter uses a hysteretic control topology to obtain maximal efficiency at minimal quiescent current.

Key Features
