TPS25750EVM: PDOs in advanced configuration not working

Sreeteja Jonnada

Part Number: TPS25750EVM

Hi,

I have a USB C sink that I only want to request 20V @5A and I want to reject all other PDOs (by going back to 5V).

I have set two PDOs in advanced settings: Just 5V and 20V, however when I plug in a source that can only provide up to 9V, I am seeing 9V on PPHV.

I want to only request 20V@5A, I want to reject 20V@3A because the produce will consume more than 60W which will overpower the charger.

What do I need to do to make this happen?

Hi,

Sorry for the delayed response.

Please see the attached binary and let me know if the issues here still persist.

Please note that for 100W, the cable that is being used must also support 5A.

Thank you,

Kevin
