Last Updated:

The CCG3PA Car Charger Reference Design Board is a receptacle based USB-C Charger with USB PD 3.0 support.  It is designed to work with standard Car Lighter Attachment (CLA). The design works with any DC input between 2.7V to 30V.

The two major components on the board are Cypress’s EZ-PD CCG3PA (CYPD3175-24LQXQT) controller and Southchip’s SC8815 DC-DC Buck-Boost controller. 

Reference design features

  • Supports USB PD 3.0 and QC3.0
  • Fixed PDO:  5V/3A, 9V/3A, 15V/3A,20V/2.25A,
  • PPS: 3V-11V/3A, 3V - 16V/3A
  • Low BOM cost with SC8815 needs 2 external MOSFET
  • CCG3PA controls SC8815 via I2C interface, including voltage and current limit

The board hardware design files (schematic,  layout etc) and firmware are readily available below for customers to reduce the design cycle.
