評估板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.
