TPS51123ARGER TI Power Management IC | 24-VQFN (4x4) | Dual Synchronous Step-Down Controller

Product Overview

The TPS51123ARGER from Texas Instruments is a dual synchronous step-down controller designed for low-power, high-efficiency power management in portable and space-constrained applications. It integrates two independent PWM controllers with adaptive on-time control, providing excellent transient response and high efficiency over a wide load range. The device operates from a 4.5V to 28V input supply and generates two regulated output voltages as low as 0.76V. Housed in a compact 24-VQFN (4x4 mm) package, it is ideal for multi-rail systems requiring small size and high performance.
