TPS628303ARZER TI Step-Down Converter | 8-WQFN-HR(1x2) | 3A, 2.4V-5.5V

Product Overview

The TPS628303ARZER from Texas Instruments is a high-efficiency, synchronous step-down (buck) converter capable of delivering up to 3A of continuous output current. It operates over a wide input voltage range of 2.4V to 5.5V, making it suitable for low-voltage power rails in portable and industrial applications. The device is housed in a compact 8-pin WQFN-HR package (1mm x 2mm) with a height of 0.4mm, ideal for space-constrained designs.
