TPS543B25RYSR TI DC-DC Converter | 17-WQFN-FCRLF (2.5X4.5) | 4.5V-18V Input, 3A Output

Product Overview

The TPS543B25RYSR from Texas Instruments is a high-efficiency, synchronous step-down DC-DC converter designed for a wide range of applications. It operates from an input voltage range of 4.5V to 18V and delivers up to 3A of continuous output current. The device integrates low on-resistance power MOSFETs and features a fixed switching frequency of 500kHz, enabling small external components. The 17-WQFN-FCRLF (2.5x4.5mm) package offers a compact solution for space-constrained designs.
