TPS51461RGET TI Power Management IC | 24-VQFN (4x4) | 2.95V-6V Input, 3A Output

Product Overview

The TPS51461RGET is a high-performance, synchronous step-down (buck) converter from Texas Instruments, designed for efficient power management in space-constrained applications. Housed in a compact 24-VQFN (4x4 mm) package, this device integrates both high-side and low-side MOSFETs to deliver up to 3A of continuous output current. With an input voltage range of 2.95V to 6V, it is ideal for systems powered by 3.3V or 5V rails, such as FPGAs, DSPs, and microcontrollers. The TPS51461RGET features a fixed 1.5MHz switching frequency, enabling small external components and fast transient response. Its advanced Eco-mode™ pulse-skipping technology ensures high efficiency at light loads, making it suitable for battery-powered devices.
