USB EZ-PD Type-C

Can the advertised PD profile have more than one of the same voltage with different currents?

For example:

5V@3A

9V@2.22A

9V@3A

15V@3A

20V@3A

The profiles in question are for the 9V. There are two of them with different max currents. Is this valid?

The reason for this is that there is a device that needs 9V@2.22A to charge. Or will it work with just advertising 9V@3A and the device will establish a contract at 9V@2.2A? Or do I need to add 9V@2.2A as a profile for this contract to be established?

Hi,

>> Yes, you can set 2 PDOs with same voltage but different currents.

But, note that 9V@3A Source PDO itself can cater to 9V@2.2A request. So, while designing a source if total power isn't a constraint then you can just include 9V@3A Source PDO.
