TPS61122PW

Power Management - Specialized Overview

The TPS61122PW is a synchronous boost converter featuring an integrated 1.1A power switch and a low-dropout regulator (LDO). It operates within an input voltage range of 1.8V to 5.5V, supporting nominal inputs of 3.3V. The device provides dual outputs: a boosted output up to 3.6V and a fixed 3.3V LDO output capable of delivering 200mA. Packaged in a 16-pin TSSOP, it integrates current-mode control for stable operation.
