USB EZ-PD Type-C

Is programmable power supported or planned to be supported in the CCGx firmware? Both as a PD-source and making a Request for a specific voltage level. Or is it possible to implement ourself? We do of course the DC/DC-communication part. Or it would require changes to the closed part of the PD-stack?

Reading the specification it would require exposing the support Programmable Power Supply or Variable Power Supply and for requesting supporting the "Programmable Request Object".

Cheers

Hi Olof,

1. Please kindly noticed that Cypress latest SDK have support PPS.

2. You are correct PPS support is not only need PD controller, but also the AC/DC or DC/DC converter can be support 20mV/steps.

3. If you are designing a power adapter, car charger, power bank solution, CCG3PA can be used. [Strong recommend]

If you are designing product with power and data support, CCG3,4,5,6 can be used.

Best Regards,

Lisa
