TPS51427ARHBT TI Dual Synchronous Buck Controller | 32-VQFN (5x5) | 4.5V-28V Input, 0.7V-5.5V Output

Product Overview

The TPS51427ARHBT is a dual synchronous buck controller from Texas Instruments, designed for high-efficiency power conversion in space-constrained applications. It integrates two independent step-down 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 output voltages from 0.7V to 5.5V, with output currents up to 20A per channel. Housed in a compact 32-pin VQFN (5x5mm) package, it is ideal for point-of-load (POL) regulation in networking, telecom, and industrial systems.
