EZ-PD™ CCG7DC dual-port USB-C power
delivery and DC-DC controller
General description
EZ-PD™ CCG7DC is Infineon highly integrated 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. Integration offered by CCG7DC not only reduces the BOM but also provides a
footprint optimized solution to support higher power density designs. CCG7DC has integrated gate drivers for
VBUS NFET on the provider path. It also includes hardware-controlled protection features on the VBUS. CCG7DC
supports a wide input voltage range (4 V to 24 V with 40 V tolerance) and programmable switching frequency (150
kHz to 600 kHz) in an integrated PD solution.
EZ-PD™ CCG7DC is the most programmable USB-PD solution with on-chip 32-bit Arm® Cortex®-M0 processor,
128-KB flash, 16-KB RAM and 32-KB ROM that leaves most flash available for user application use. It also includes
various analog and digital peripherals such as ADC, PWMs and Timers. The inclusion of a fully programmable MCU
with analog and digital peripherals allows the implementation of custom system management functions such as
dynamic load sharing and temperature monitoring.
