    Hello JH,

    thanks for reaching out in E2E.

    The output capacitance is pretty high. I would recommend to verify stability of this output filter design.

    The output voltage sense pin (VOS) must be directly connected to the output capacitor.

    The rest of the schematic is OK.

    Best regards,

    Andreas.
