TPS54334DDA TI DC-DC Converter | 8-SO-POWERPAD | 3A, 4.5V-28V Input

Product Overview

The TPS54334DDA is a high-efficiency, synchronous step-down DC-DC converter from Texas Instruments. It integrates a low RDS(on) high-side and low-side MOSFETs to deliver up to 3A continuous output current. With a wide input voltage range of 4.5V to 28V, it is ideal for systems powered from 5V, 12V, or 24V rails. The device operates at a fixed 570kHz switching frequency, enabling small external components. The 8-SO-POWERPAD package enhances thermal performance, making it suitable for space-constrained applications.
