Team,
are the Type-C controllers capable to compensate the Vbus power loss caused by the cable between DCDC (Vbus) and the PD controller?
Thanks!

Hi,
No, PD controller cannot compensate cable loss.
If you don't have further queries, Could you click "This resolved my issue" to close this thread ?

Hi,
I hope you are trying to compensate the loss on the trace b/w DCDC regulator and PD controller when acting as source. Why don't you adjust DCDC regulator feedback resistors to give positive offset at o/p? Since the trace length is fixed (so the loss) this approach should be fine.
Thanks

Prajith,
yes, this is meant to compensate the loss on the cable between DCDC regulator and PD controller when acting as source.
The compensation needs to be dynamic since the cabling will vary depending on where the equipment is placed.
Best regards
Hey,
Do you mean to compensate for the IR drop on the Type-C cable b/w a Source and Sink port? If yes, the maximum drop is limited by spec. Please find section 4.4 Power and Ground 4.4.1 IR drop in Type C Spec.
Thanks
