    Hi Hideyuki,

    C17 sits in the wrong place. Please see the datasheet.

    Hi Hideyuki,

    If you are not planning to use the XTR111 voltage regulator, please short REGF and REGS together and install a 470nF bypass capacitor as suggested on Figure 45 of the XTR111 datasheet.

    As Kai has mentioned, please connect C17 to the drain of Q11 (refer to Figure 36 of the datasheet).

    Many Thanks,

    Kind Regards,

    Luis
