评估板CY4532 EZ-PD™ CCG3PA EVK

The CY4532 EZ-PD™ CCG3PA Evaluation Kit (EVK) is based on the CCG3PA product family of Cypress’ USB Type-C microcontrollers. This EVK is intended to be an evaluation vehicle for USB Type-C Power Adapter (PA) and USB Type-C Power Bank (PB) applications. The kit can be configured for a PA or PB application using a combination of firmware, jumper settings on the kit hardware, and external accessories. The following paragraphs provide a brief description of both applications:

USB Type-C Power Adapter (PA): This application is used to charge a device such as a mobile phone or notebook, which supports their battery charging through the Type-C interface. The device can be connected to the Type-C port or Type-A port on the CY4532 EVK’s Main Board. This application requires a DC input to be supplied to the EVK.

USB Type-C Power Bank (PB): This application uses a 1-Cell or 2-Cell Lithium-ion battery connected to the CY4532 EVK, which acts as the power source to support charging on USB Type-C and USB Type-A ports. In addition, the battery can be charged using a USB Type-C Power Adapter connected to the USB Type-C port of the EVK’s Main Board.

In addition to the applications described above, the CY4532 Power Board can be used as a Programmer for Cypress EZ-PD CCGx Products supporting Configuration Channel (CC) boot-loading. See Chapter 5. Kit Operation for more details.
