Hi Ti Engineer,

We are working on a design based on Gorilla Creek TI88.

The PDO set to 5V/3A-9V/3A-15V/3A-20V/4.25A in TPS65988DK for port A.

TPS65988_85W PDO

TPS65982_85W_115W

But from the PD Analyzer & host side found . The source still advertise as 20V 5A.

PD_log_100Wcap

Seems like abnormal.

Hi Aya,

Any progress about this case?

I also tried gui Build 6.3.7, seems like the same.

Hi Clarence,

Thank you for your patience.

I am working with the team on identifying what could be causing this. My thought is that it may be related to the DMC. I will provide some more updates early next week.

Best Regards,
