TPS55189QWRYQRQ1 TI Buck-Boost Converter | 21-VQFN-HR (3x5) | 2.7V-16V Input, 3.5A Switch

Product Overview

The TPS55189QWRYQRQ1 is a high-efficiency, low-quiescent-current buck-boost converter from Texas Instruments, designed for automotive and industrial applications. It operates over a wide input voltage range of 2.7V to 16V and can deliver up to 3.5A of switch current. The device integrates four N-channel MOSFETs and provides seamless transition between buck and boost modes, making it ideal for battery-powered systems where input voltage varies above and below the output voltage. The TPS55189QWRYQRQ1 is available in a compact 21-pin VQFN-HR package (3mm x 5mm) and is AEC-Q100 qualified for automotive applications.
