We have a design, tightly based on reference design "39W Dual Port Car Charger" https://www.cypress.com/documentation/reference-designs/ez-pd-ccg3pa-usb-c-pps-39w-dual-port-car-cha...

We need the source code project; the SDK project CYPD3171-24LQXQ_cla is missing the control interfaces for both Active Semi dc/dc converters.

Can one of the Cypress guys provide me this project.

Thanks in advance.

Hi Lisa,

thanks for the quick response.

I investigated the sources and have some concerns.

The topdesign/pin-mapping does not correspond with the electronics design.

ACT4751 is implemented in stead of ACT5101

In the software, some essential code is missing: e.g. ACT2_SetVolt is called nowhere; voltage control of the ACT2861 seems not to be implemented. This makes it impossible to be functional.

Also the selected CPU doesn't match.

So, I have my doubts that this is the final release.

Regards,

Wim
