TPS54561DPRT TI Step-Down Converter | 10-WSON (4x4) | 5A, 4.5V-60V

Product Overview

The TPS54561DPRT is a high-performance, 5A step-down (buck) converter from Texas Instruments, designed for wide input voltage range applications. Housed in a compact 10-WSON (4x4) package, it integrates a low RDS(on) high-side MOSFET to achieve high efficiency and excellent thermal performance. The device operates at a fixed switching frequency of 400 kHz, enabling small external components while maintaining low output ripple.
