TPS51621RHAT TI Power Management IC | 40-VQFN (6x6) | Dual-Phase, PWM Controller

Product Overview

The TPS51621RHAT is a high-performance, dual-phase, step-down controller from Texas Instruments, designed for non-isolated DC/DC conversion in point-of-load (POL) applications. It integrates a PWM controller with a built-in gate driver and supports Intel VR12/IMVP7 voltage regulation. The device operates from a 4.5V to 28V input supply and provides an adjustable output voltage down to 0.5V with ±0.5% accuracy. Housed in a compact 40-pin VQFN (6x6 mm) package, it offers high efficiency and fast transient response.
