TPS51375LVBHR TI DC-DC Converter | 19-WQFN-FCRLF(4X3) | 3A, 2.5V to 5.5V

Product Overview

The TPS51375LVBHR from Texas Instruments is a high-efficiency, synchronous step-down DC-DC converter capable of delivering up to 3A of continuous output current. It operates from an input voltage range of 2.5V to 5.5V, making it ideal for low-voltage power rails in modern electronic systems. The device integrates low RDS(on) power MOSFETs and uses a fixed-frequency, peak-current-mode control architecture for fast transient response and stable operation. Housed in a compact 19-pin WQFN-FCRLF package (4mm x 3mm), it is optimized for space-constrained applications.
