TPS51125ARGER TI Power Management IC | 24-VQFN (4x4) | Dual Synchronous Step-Down Controller

Product Overview

The TPS51125ARGER from Texas Instruments is a dual, synchronous step-down controller optimized for low-power system applications. It integrates two independent pulse-width modulation (PWM) controllers with adaptive on-time D-CAP™ mode for fast transient response. The device operates from a 4.5V to 28V input supply and provides two adjustable output voltages down to 0.76V with ±1% accuracy. Housed in a compact 24-VQFN (4x4) package, it is ideal for space-constrained designs requiring high efficiency and reliability.
