TPS51220RHBR TI Power Management IC | 32-VQFN (5x5) | Dual 3-A, 2-Phase Step-Down Controller

Product Overview

The TPS51220RHBR from Texas Instruments is a high-performance, dual-output, 2-phase step-down controller designed for point-of-load (POL) regulation in computing, networking, and industrial applications. It integrates two synchronous buck controllers with a 3-A gate drive capability per phase, supporting output voltages as low as 0.6 V. The device operates from a 4.5-V to 28-V input supply and provides excellent transient response and high efficiency over a wide load range. Housed in a compact 32-pin VQFN (5x5 mm) package, the TPS51220RHBR is ideal for space-constrained designs requiring precise voltage regulation and high current density.
