Hi all,
We used the CYPD4226-40LQXIT before on another project that for USB-C PD with 100W max and it is working fine. For this new design I tried to use the same PD circuit to two USB-C ports but due to the input power limitation we could only have one USB-C port with full PD function (100W max) and another USB-C port with 5V @ 1.5A output only. Can the CYPD4226-40LQXIT can program to output only 5V @ 1.5A max even the connected target device support full range?
Thanks

Hello Joe,
Thank you for posting on Infineon Community.
Q) Can the CYPD4226-40LQXIT can program to output only 5V @ 1.5A max even the connected target device support full range?
A) Yes.
CCG4 can have different settings for both ports.
You can easily change the settings using EZ-PD Configuration Utility.
In the image above, I have added the 20V 5A source PDO to Port 0, which will be the port supplying up to 100W.
For Port 1 however, I removed all source PDOs except for PDO 0, in which I have set the maximum current as 1.5 A.
This way you can have the port settings you are looking for.
(Please understand that each port needs to have a separate VBUS converter)
Let me know if this helped in your design.
Best regards,
Pablo
