TPS5431DDAR TI DC-DC Converter | 8-SO-POWERPAD | 3A Output, 4.5V-28V Input

Product Overview

The TPS5431DDAR is a high-performance, 3A step-down (buck) DC-DC converter from Texas Instruments, designed for applications requiring high efficiency and compact size. It operates over a wide input voltage range of 4.5V to 28V and delivers up to 3A of continuous output current. The device is housed in an 8-pin SO PowerPAD package, which enhances thermal performance. With integrated MOSFETs and a fixed 500kHz switching frequency, the TPS5431DDAR simplifies design while providing excellent transient response and regulation.
