TPS546B25RXXR TI DC/DC Converter | 37-WQFN-FCRLF(5X6) | 4.5V-18V Input, 6A Output

Product Overview

The TPS546B25RXXR from Texas Instruments is a high-performance, synchronous step-down DC/DC converter designed for space-constrained applications. It integrates high-side and low-side MOSFETs to deliver up to 6A continuous output current with excellent efficiency. The device operates over a wide input voltage range of 4.5V to 18V, making it suitable for a variety of power rails in industrial, telecom, and automotive systems. Housed in a compact 37-pin WQFN-FCRLF package (5mm x 6mm), it offers a small footprint while maintaining thermal performance.
