    Tateo,

    The LM5140-Q1 is a current mode controller, so the feed forward capacitor for most applications is not required. If your customer would like to add it, there are no technical concerns. Make sure your customer checks the control loops phase and gain margin to be sure the capacitor does not cause any issues.
