TPS51220ARTVR TI Power Management IC | 32-WQFN (5x5) | Dual Step-Down Controller

Product Overview

The TPS51220ARTVR from Texas Instruments is a highly integrated, dual-channel step-down (buck) controller designed for efficient power conversion in a wide range of applications. It operates over a wide input voltage range from 4.5V to 28V and provides two independent output voltages adjustable from 0.7V to 5.5V. The device features fixed-frequency operation at 300kHz or 600kHz, selectable via a pin, and incorporates advanced power-saving modes to maintain high efficiency across the load range. Housed in a compact 32-pin WQFN (5x5 mm) package, the TPS51220ARTVR is ideal for space-constrained designs requiring high power density.
