TPS63021DSJT TI Buck-Boost Converter | 14-VSON(4x3) | 2.5-5.5V, 3.6A

Product Overview

The TPS63021DSJT from Texas Instruments is a high-efficiency, low-quiescent-current buck-boost converter capable of delivering up to 3.6A output current. It operates from a single-cell Li-Ion battery or standard 3.3V/5V rails, providing a regulated output voltage from 2.5V to 5.5V. The device seamlessly transitions between buck and boost modes, ensuring stable output even when input voltage varies above or below the output. Housed in a compact 14-pin VSON (4x3 mm) package, it is ideal for space-constrained applications requiring high power density.
