CCS/UCD3138PFCEVM-026: About the single-phase Boost PFC official routine PWR026_PFC

Part Number: UCD3138PFCEVM-026

Tool/software: Code Composer Studio

Hello, I am currently trying to imitate the UCD3138PFCEVM-026 evaluation board to make a low-voltage single-phase Boost PFC board.

I tried to input the input voltage to 10~15V and the output voltage to 25V.

But when I modified the input and output voltages in the PWR026_PFC code, the 3138 did not work properly.

How can I change the code, can you help me?
