EZ-PD™ CCG7D Consumer : Dual-port USB-C PD controller with integrated Buck-Boost controller

EZ-PD™ CCG7D is a highly integrated and programable dual-port USB Type-C Power Delivery (PD) solution with integrated Buck-Boost controllers. It complies to the latest USB Type-C and PD specifications, and is targeted for multi-port consumer charging applications.

CCG7D supports a wide input voltage range (4V-24V with 40V tolerance) and programmable switching frequency (150 kHz-600 kHz) in an integrated PD solution. Integration offered by CCG7D not only reduces the BOM but also provides a footprint optimized solution to support higher power density designs.

CCG7D supports advanced features such as dynamic load-sharing, signed field firmware upgrade, and optimized buck input voltage.
