TPS51427RHBT TI Power Management IC | 32-VQFN (5x5) | Dual Synchronous Buck Controller

Product Overview

The TPS51427RHBT from Texas Instruments is a high-performance, dual-output, synchronous buck controller designed for efficient power management in demanding applications. It integrates two independent step-down controllers with adaptive on-time control, providing excellent transient response and high efficiency over a wide load range. The device operates from a 4.5V to 28V input supply and delivers output voltages as low as 0.7V, making it suitable for powering core voltages in computing and telecom systems. Housed in a compact 32-VQFN (5x5 mm) package, the TPS51427RHBT offers a space-saving solution for high-density power designs.
