TPS548A28RWWR TI DC-DC Converter | 21-VQFN-HR (4x3) | 4.5V-17V Input, 8A Output

Product Overview

The TPS548A28RWWR is a high-performance, synchronous step-down DC-DC converter from Texas Instruments, designed for space-constrained applications requiring high efficiency and small solution size. It operates over a wide input voltage range of 4.5V to 17V and delivers up to 8A of continuous output current. The device is housed in a compact 21-pin VQFN-HR package (4mm x 3mm), making it ideal for point-of-load (POL) regulation in telecom, networking, and industrial systems.
