Hi @jialf521,

 

Since you are inserting new MAX15303 Regulator, it will not be programmed.

You need to do power controller reprogramming by following this AR#66811. after that you will get required voltage at output.

Thank you @ddn

      After replacing the MAX15303 chip, it is found that the output voltage is different from that before. The output voltage before replacing is 3.3v and now it is 1.89v. I don't know whether there is a problem with the replaced chip or because there is no reprogramming in the replaced chip.After replacing the MAX15303 chip, will it not work if the chip is not reprogrammed according to AR#66811.

 

  Thank you for your reply.
