    Hi Bogey,

    It's up the customer if they want to include bode plot measurements in their validation plan. It's certainly not a bad thing to check but if transient response looks fine then bode plots sometimes get omitted.

    You can learn more about taking these measurements in the following app note from a Power Supply Design Seminar.

    Cheers,
