TPS628304ARZER TI Step-Down Converter | 8-WQFN-HR(1x2) | 4A, 2.4V-5.5V

Product Overview

The TPS628304ARZER from Texas Instruments is a high-efficiency, synchronous step-down (buck) converter capable of delivering up to 4A of continuous output current. It operates from an input voltage range of 2.4V to 5.5V, making it ideal for low-voltage power rails in modern electronics. The device is housed in a compact 8-pin WQFN-HR package with a 1mm x 2mm footprint, enabling space-constrained designs. With a switching frequency of 2.4MHz, it allows the use of small external inductors and capacitors, reducing overall solution size.
