1. After setting the output PD 20V / 3.25A, when checking the output, PD 20V / 3A is applied.

Hi,

 

In order to advertise PDO greater than 3A, CCG3PA verifies whether cable is capable of handling current greater than 3A. If cable is EMCA and if it allows up to 5A of current CCG3PA advertises those PDOs.

To enable operation beyond 3A, please follow the steps in given articles.

1. Please refer to "How do I add VCONN support to EVK?" question from the KBA -  Frequently Asked Questions on CY4532 CCG3PA Kit – ... - Cypress Developer Community

2. Enable cable discovery by following steps in the article -  Enabling Cable Discovery in CCGx Power SDK Firmwar... - Cypress Developer Community

Source Power adapter and Power bank projects for the CY4532 kit can be found in CCGx Power SDK - https://www.cypress.com/documentation/software-and-drivers/ez-pd-ccgx-power-software-development-kit

Best regards,
Pranava
