TPS54357PWPR TI Step-Down Converter | 16-HTSSOP | 3A, 4.5V-28V

Product Overview

The TPS54357PWPR is a high-performance, 3A step-down (buck) converter from Texas Instruments, housed in a compact 16-HTSSOP package. It integrates a low RDS(on) MOSFET and operates over a wide input voltage range of 4.5V to 28V, making it suitable for a variety of power supply designs. The device features a fixed 500kHz switching frequency, which allows for small external components and reduces output ripple. With its high efficiency and robust protection features, the TPS54357PWPR is an ideal solution for powering FPGAs, DSPs, and other sensitive loads in industrial, automotive, and telecommunications applications.
