Hello,I try to download the program (PWR026_PFC) to UCD3138CC64EVM - 030, but showed" No PMBus devices responded to a DEVICE_ID request".

Then, I tried to connect the fault3 pin to DGND, but without any effect.

Can you help me?

Looking at the code, it's fault 1 that you want to pull to ground, not fault 3.

Hello, I am doing a single phase PFC now.

I want to try the input voltage is 10~15V, the output voltage is 30V, DPWM-1B is the PWM output pin,and the other sampling pins are imitated UCD3138PFCEVM-026.

I changed the input voltage and output voltage in the PWR026_PFC code, but the 3138 is not working properly.

How can I change the code?

can you help me?

I think this has moved to either another E2E message or direct support, so I'm going to close this.
