TPS53129RGER TI Power Management IC | 24-VQFN (4x4) | Dual Synchronous Step-Down Controller

Product Overview

The TPS53129RGER from Texas Instruments is a dual synchronous step-down controller designed for low-voltage, high-current power supply applications. It integrates two independent pulse-width modulation (PWM) controllers with adaptive on-time control architecture, enabling fast transient response and high efficiency. The device operates from a 4.5V to 24V input voltage range and provides two adjustable output voltages down to 0.76V with ±1% accuracy. Housed in a compact 24-pin VQFN (4x4 mm) package, it is ideal for space-constrained designs requiring dual output rails.
