USB-C charging reference design help engineers speed their design time

17-12-2019 | Mouser Electronics | Design & Manufacture

Mouser offers a new USB Type-C charging hub reference design from Qorvo and Cypress Semiconductor to aid engineers to speed their design and development time.

The reference design incorporates the Qorvo ACT4751 DC-to-DC buck converter and a Cypress EZ-PD CCG3PA USB Type-C and PD controller. The reference design and products support applications including PC and tablet power adapters, vehicle chargers, smartphone and mobile chargers, and power banks.

The Qorvo ACT4751 is a high-efficiency, synchronous step-down DC-DC converter with a wide 4.5V-40V input range. The device uses a proprietary control algorithm and controls two integrated 50mOhm MOSFETs to attain very high efficiency and facilitate remarkably compact designs.

The Cypress EZ-PD CCG3PA controller supports USB-C power source and dual-role power source/sink. Furthermore, the controller wholly supports the USB PD 3.0 PPS specification, which enables smartphones to communicate with the charger to define the best voltage and current levels. The controller's Quick Charge 4 certification also includes enhanced safety features to assure fast charging with no overheating.

Together, the devices form the foundation of a USB-C/USB-A charging power hub reference design. The solution is a receptacle-based Type-C power adapter supporting a maximum power profile of 80W (20V, 4A), along with a legacy Type-A port with a maximum output of 60W (20V, 3A when activating Quick Charge 3).
