MAX77963 Overview
The MAX77963 is a high-performance wide-input 3.2A buck-boost charger with a Smart Power Selector™ and operates as a reverse buck without an additional inductor, allowing the IC to power USB On-the-Go (OTG) accessories. The device integrates low-loss power switches and provides a small solution size, high efficiency, low heat, and fast battery charging. The reverse buck has a true-load disconnect and is protected by...
