TPS55285VALR TI Buck-Boost Converter | 15-WQFN-HR(2.5X3.5) | 2.7V-36V Input, 5A Output

Product Overview

The TPS55285VALR from Texas Instruments is a high-performance, synchronous buck-boost converter designed to provide a regulated output voltage from input voltages that can be either above, below, or equal to the output. It operates over a wide input voltage range of 2.7V to 36V and can deliver up to 5A of continuous output current. The device is housed in a compact 15-pin WQFN-HR package measuring 2.5mm x 3.5mm, making it ideal for space-constrained applications. With integrated power MOSFETs and a programmable switching frequency from 200kHz to 2.2MHz, the TPS55285VALR offers high efficiency and design flexibility.
