    Hello CT,
    I reviewed your schematic and I recommend the following:
    (1) Please use the Excel calculator tool to calculate the component values for your design
    (2) Im not sure where the UCC2897A gets its VDD rail from. Where does VCOUT come from.
    (3) VCIN is a bias supply generated by the power transformer. Is this connected to VDD ?

    All of the connection on the schematic for the UCC2897A look like they are properly connected.
    I did not see any other issue to comment on.
    Regards
    John

    Hi John,

    Thanks for your help.

    All the connection is following the TPS2373EVM for your reference, the VCOUT is coming from TPS2373

    Thank you.
