This datasheet includes multiple variants, all published together in a single manufacturer document.

General Description

The MAX77960/MAX77961 are high-performance wideinput 3A (MAX77960)/6A (MAX77961) buck-boost chargers with Smart Power Selector™ and operate as a reverse buck converter without an additional inductor, allowing the ICs to power USB on-the-go (OTG) accessories.

The devices integrate low-loss power switches and provide high efficiency, low heat, and fast battery charging in a small solution size.

The reverse buck has true load disconnect and is protected by an adjustable output current limit.
