TPS551892QWRYQRQ1 TI Buck-Boost Converter | 21-VQFN-HR (3x5) | 2.2V-5.5V, 3A

Product Overview

The TPS551892QWRYQRQ1 from Texas Instruments is a high-efficiency, low-quiescent-current buck-boost converter designed for automotive and industrial applications. It operates from a 2.2V to 5.5V input voltage range and delivers up to 3A output current. The device integrates four power MOSFETs and provides seamless transition between buck and boost modes, ensuring regulated output even when input voltage varies above or below the output. Housed in a compact 21-VQFN-HR (3x5) package, it is ideal for space-constrained designs requiring high reliability.
