The CY4541 EZ-PD CCG4 EVK has a power provider and power consumer path control circuitry to showcase CCG4
’s ability to
switch its power role from a provider to a consumer and vice-versa. This EVK has overvoltage and overcurrent protection circuitry
for VBUS and VCONN; it also supports programming CCG4 devices over SWD and I2C interfaces.
A PC with two USB 3.0 ports and a DisplayPort along with the CY4541 EZ-PD CCG4 EVK is equivalent to a PD-enabled dual
Type-C port PC.

The following sections describe the CCG EVK base board and daughter card design.
4.3 CCG EVK Base Board
The CCG EVK base board is an evaluation board equipped with a Type-C port, a SuperSpeed USB Type-B port, and a DisplayPort
interface. It is primarily intended as a demonstration board for PC designs that house a Type-C connector. The board also serves
as a vehicle to evaluate the alternate Type-C modes, using the DisplayPort demo as an example.
4.3.1 Block Diagram
shows the CCG EVK base board block diagram. It has an onboard Type-C connector for the USB-PD interface and a
CY4541 CCG4 daughter card interface connector to connect the CY4541 CCG4 daughter card. It also includes a SuperSpeed
USB Type-B port and a DisplayPort connector to source video. The SuperSpeed USB signals and DisplayPort signals are
connected to the Type-C connector through a display multiplexer controlled by the CCG4 device. A DC power adapter provides
input voltage to the onboard Power Management IC (PMIC). The output voltage from the PMIC can be selected using two voltage
selection lines, controlled by CCG4. This CCG EVK base board, along with the CY4541 CCG4 daughter card, helps convert any
desktop or notebook PC with legacy USB ports to operate as a Type-C USB host.
