TPS51225CRUKR TI Power Management IC | 20-WQFN (3x3) | Dual Step-Down Controller

Product Overview

The TPS51225CRUKR from Texas Instruments is a dual-channel, synchronous step-down controller designed for high-efficiency power conversion in space-constrained applications. Housed in a compact 20-pin WQFN (3x3 mm) package, this device integrates two independent PWM controllers with adaptive on-time D-CAP™ mode control, enabling fast transient response and minimal external components. It operates over a wide input voltage range of 4.5V to 28V, making it suitable for 5V, 9V, 12V, and 19V rails commonly found in consumer electronics, networking, and industrial systems. Each output can be adjusted from 0.76V to 5.5V, delivering up to 15A per channel with excellent load and line regulation. The device features programmable switching frequency (200 kHz to 1.2 MHz), allowing optimization between efficiency and component size. Protection features include overcurrent protection (OCP), overvoltage protection (OVP), undervoltage lockout (UVLO), and thermal shutdown.
