　　The CCG2 device on the board handles USB Type-C interface and PD 2.0 whereas AC-DC power conversion, Over Current Protection (OCP) and Over Voltage Protection (OVP) are handled by Dialog Semiconductor’s iW1782-00 AC-DC controller, which supports universal AC input supply. The board hardware design files (schematic, bill of materials and board files) are readily available below for customers to reduce the design cycle.
