TPS55289RYQR TI Buck-Boost Converter | 21-VQFN-HR(3X5) | 2.7V-36V, 6A

Product Overview

The TPS55289RYQR from Texas Instruments is a high-performance, synchronous buck-boost converter with a wide input voltage range of 2.7V to 36V and an output current capability of up to 6A. Housed in a compact 21-pin VQFN-HR (3x5mm) package, this device is designed for applications requiring a regulated output voltage that can be either higher or lower than the input voltage. It integrates four low RDS(on) power MOSFETs and features a programmable switching frequency from 200kHz to 2.2MHz, enabling efficient power conversion in a small footprint.
