TPS40422RSBT TI Power Management IC | 40-WQFN (5x5) | Dual 4.5V-20V, 2-Phase Controller

Product Overview

The TPS40422RSBT from Texas Instruments is a dual-output, multi-phase synchronous buck controller designed for high-current, low-voltage applications. It integrates PMBus interface for telemetry and configuration, supporting up to 2 phases per output. The device operates from a 4.5V to 20V input voltage range and provides adjustable output voltage down to 0.6V with ±0.5% accuracy. Housed in a compact 40-WQFN (5x5 mm) package, it is ideal for space-constrained designs requiring high efficiency and precise regulation.
