    Hi Kygo Cheng,

    Looks like customer wants to realize input reverse polarity protection using LM5050-1. You can promote LM74700-Q1 which has integrated reverse current blocking + Input reverse current blocking.

    The LM5050-1 schematics look good to me. It is recommended to add a decoupling capacitor (1uF) at the input to suppress noise on the power line and avoid false trigger of Gate.
