TPS65721RSNT TI PMIC | 32-QFN（4X4） | 2.5A Step-Down Converter, 300mA LDO

Product Overview

The TPS65721RSNT from Texas Instruments is a highly integrated power management IC (PMIC) designed for space-constrained applications. It combines a 2.5A step-down DC-DC converter with a 300mA low-dropout (LDO) regulator in a compact 32-pin QFN package (4mm x 4mm). The device operates from a 2.5V to 6V input voltage range, making it suitable for battery-powered systems and multi-rail power architectures. With high efficiency and low quiescent current, the TPS65721RSNT extends battery life in portable devices while delivering clean and stable power rails.
