TPS54308DDCR TI 4.5V-28V 3A Step-Down Converter | SOT-23-THIN | 600kHz, Eco-mode

Product Overview

The TPS54308DDCR is a high-performance, 3A step-down (buck) converter from Texas Instruments, designed for space-constrained applications. It operates over a wide input voltage range of 4.5V to 28V and delivers up to 3A of continuous output current. Housed in a compact SOT-23-THIN package, this device integrates high-side and low-side MOSFETs, minimizing external component count. The TPS54308 features Eco-mode™ for high efficiency at light loads, a fixed 600kHz switching frequency, and internal compensation, simplifying design and reducing solution size.
