If 5V is taken out from AC12V5A using DCDC converter and supplied to PSOC4, only capsense operation will be stopped.
We can confirm that high / low switches during loops such as pin.
It works with no problem with input from kitprog. It works even if you put 12v later.
Is there anything wrong?

Hi,
Can you check if you have supplied power to VDDA as well? Also can you probe the cmod pin and check it's voltage?

hi Bragadeesh
Thank you for answering!
Normal operation(kitprog)
vdda is 4.5v
cmod is 1.2v
When not working(AC12V5A )
vdda is 4.6v
cmod is 4.1v
Certainly I could confirm the difference.
I will check it for myself,
If there is a solution, please answer.
