TPS51427ARHBR TI Dual Synchronous Buck Controller | 32-VQFN (5x5) | 4.5V-28V Input, 0.7V-5.5V Output

Product Overview

The TPS51427ARHBR is a dual-channel, synchronous buck controller from Texas Instruments, designed for high-efficiency power conversion in space-constrained applications. Housed in a compact 32-pin VQFN (5x5 mm) package, it integrates two independent step-down controllers with adaptive on-time D-CAP™ mode control for fast transient response. The device operates from a 4.5V to 28V input supply and provides adjustable output voltages from 0.7V to 5.5V, making it suitable for a wide range of point-of-load (POL) regulation needs.
