TPS51275B-1RUKT TI Power Management IC | 20-WQFN (3x3) | Dual Synchronous Buck Controller

Product Overview

The TPS51275B-1RUKT is a dual-channel, adaptive on-time D-CAP™ mode synchronous buck controller from Texas Instruments. It integrates two independent step-down controllers with a wide input voltage range of 4.5V to 28V, making it suitable for various power supply designs. The device features a 0.6V reference voltage with ±1% accuracy, supporting output voltages as low as 0.6V. Housed in a compact 20-pin WQFN (3x3 mm) package, it offers high efficiency and fast transient response for space-constrained applications.
