TPS51621RHAR TI Power Management IC | 40-VQFN (6x6) | Dual-Phase, D-CAP+

Product Overview

The TPS51621RHAR from Texas Instruments is a highly integrated, dual-phase, D-CAP+ mode step-down controller designed for high-performance power management in computing and telecom systems. It operates from a 4.5V to 24V input supply and provides an adjustable output voltage down to 0.5V with ±1% accuracy. The device features a 0.5% reference voltage accuracy, 300kHz to 1.2MHz switching frequency, and supports both ceramic and electrolytic output capacitors. Housed in a compact 40-pin VQFN (6x6mm) package, it offers excellent thermal performance and space savings.
