TPS65561RGTT TI Power Management IC | 16-VQFN (3x3) | 4.5V-15V Input, 2.5A Output

Product Overview

The TPS65561RGTT from Texas Instruments is a high-performance, step-down (buck) DC-DC converter designed for power management in space-constrained applications. Housed in a compact 16-pin VQFN (3x3 mm) package, this device delivers up to 2.5A of continuous output current with excellent efficiency. It operates over a wide input voltage range of 4.5V to 15V, making it suitable for a variety of systems including industrial, automotive, and telecommunications equipment. The TPS65561RGTT integrates a low RDS(on) N-channel MOSFET and features a fixed 500kHz switching frequency to minimize external component size. With built-in protection features such as overcurrent, overvoltage, and thermal shutdown, it ensures reliable operation in demanding environments.
