TPS5124DBT TI Power Management IC | 30-TSSOP | Dual Synchronous Step-Down Controller

Product Overview

The TPS5124DBT from Texas Instruments is a dual-output, synchronous step-down controller designed for high-efficiency power conversion in space-constrained applications. It integrates two independent PWM controllers with adaptive on-time control, enabling fast transient response and minimal output capacitance. Operating from a 4.5V to 28V input supply, it generates two regulated outputs as low as 0.9V with ±1% accuracy. The device is housed in a compact 30-pin TSSOP package, making it ideal for telecom, networking, and industrial systems.
