TPS51120RHBR TI Power Management IC | 32-VQFN (5x5) | Dual Synchronous Buck Controller

Product Overview

The TPS51120RHBR from Texas Instruments is a dual, synchronous buck controller designed for low-voltage, high-current power supply applications. It integrates two independent pulse-width modulation (PWM) controllers with adaptive on-time D-CAP™ mode control, enabling fast transient response and minimal external components. The device operates from a 4.5V to 28V input voltage range and provides two regulated outputs down to 0.76V with ±1% accuracy. Housed in a compact 32-pin VQFN (5x5 mm) package, it is ideal for space-constrained designs requiring high efficiency and reliability.
