TPS65735RSNR TI PMIC | 32-QFN（4X4） | 2.7V-5.5V, 3A Buck, 2 LDOs

Product Overview

The TPS65735RSNR is a highly integrated power management IC (PMIC) from Texas Instruments, designed for space-constrained and power-sensitive applications. It features a high-efficiency step-down converter (buck) capable of delivering up to 3A output current, along with two low-dropout regulators (LDOs) providing 300mA and 150mA respectively. The device operates from a single Li-Ion battery or standard 3.3V/5V rails, with an input voltage range of 2.7V to 5.5V. The 32-pin QFN package (4mm x 4mm) enables compact PCB layouts, making it ideal for portable electronics, industrial sensors, and wireless infrastructure.
