TPS51220RHBT TI Power Management IC | 32-VQFN (5x5) | Dual Synchronous Step-Down Controller

Product Overview

The TPS51220RHBT from Texas Instruments is a dual-channel, synchronous step-down controller designed for high-efficiency power conversion in a compact 32-VQFN (5x5 mm) package. It integrates two independent PWM controllers with adaptive on-time D-CAP™ mode control, enabling fast transient response and minimal external components. The device operates from a 4.5V to 28V input voltage range and provides adjustable output voltages down to 0.76V with ±1% accuracy. Its high-side and low-side MOSFET drivers support up to 20A per channel, making it ideal for point-of-load regulation in computing, networking, and industrial systems.
