TPS51285BRUKR TI Power Management IC | 20-WQFN (3x3) | Dual Buck Controller

Product Overview

The TPS51285BRUKR from Texas Instruments is a highly integrated, dual-channel step-down (buck) controller designed for notebook and tablet power systems. It features D-CAP+™ mode control for fast transient response and supports both 5V and 3.3V system rails. The device operates from a 4.5V to 24V input voltage range and provides two independent output voltages adjustable via external resistors. With integrated MOSFET drivers and a 20-pin WQFN (3x3 mm) package, it offers a compact solution for space-constrained applications.
