TPS51727RHAR TI Power Management IC | 40-VQFN (6x6) | Dual Output, Step-Down Controller

Product Overview

The TPS51727RHAR from Texas Instruments is a high-performance, dual-output, step-down (buck) controller designed for point-of-load (POL) regulation in advanced computing and telecom systems. It integrates two synchronous buck controllers with a wide input voltage range of 4.5V to 28V, delivering output voltages as low as 0.6V with high efficiency. Housed in a compact 40-pin VQFN (6x6 mm) package, it supports up to 20A per phase with external MOSFETs, making it ideal for space-constrained, high-current applications.
