  • Hello

    The best way to determine if a Cff is needed, and what value to use, is to design the application using the Webench Design tool.

    It is prudent to leave a space on the PCB for both Cff and Rff in case they are needed.

    A load transient test is the best way to examine the effects of using a Cff.

    Thanks
