TPS54331DR TI DC-DC Converter | 8-SOIC | 3A, 28V Input, 570kHz

Product Overview

The TPS54331DR is a 3A, step-down (buck) DC-DC converter from Texas Instruments, designed for high-efficiency power conversion in space-constrained applications. It operates over a wide input voltage range of 3.5V to 28V and delivers an adjustable output voltage down to 0.8V. The device integrates a 100mΩ high-side MOSFET and uses current-mode control for fast transient response and stable operation. Housed in an 8-pin SOIC package, it is ideal for point-of-load regulation in industrial, automotive, and telecom systems.
