TPS40322RHBT TI DC/DC Controller | 32-VQFN (5x5) | 600kHz, 4.5V-15V Input

Product Overview

The TPS40322RHBT from Texas Instruments is a high-performance, synchronous buck controller designed for low-voltage, high-current power conversion. It operates from a 4.5V to 15V input supply and delivers a regulated output voltage as low as 0.6V with ±1% accuracy. The device features a fixed 600kHz switching frequency, integrated gate drivers, and a comprehensive set of protection features including overcurrent, overvoltage, and thermal shutdown. Housed in a compact 32-pin VQFN (5x5mm) package, it is ideal for space-constrained applications requiring high efficiency and reliability.
