TPS65251RHAR TI Power Management IC | 40-VQFN (6x6) | 3 Buck Converters, 4.5V-18V Input

Product Overview

The TPS65251RHAR from Texas Instruments is a highly integrated power management IC (PMIC) designed for multi-rail applications. It features three synchronous step-down (buck) converters with a wide input voltage range of 4.5V to 18V, making it suitable for systems powered by 5V, 9V, 12V, or 15V rails. The device is housed in a compact 40-pin VQFN package (6mm x 6mm) with a 0.5mm pitch, enabling space-efficient designs. Each converter provides adjustable output voltages down to 0.8V with high efficiency up to 95%. The TPS65251RHAR integrates power MOSFETs, compensation, and protection features, reducing external component count and simplifying layout.
