    Hi Neal,

    thanks for your input.

    the customer stated that with an existing rating the resulting crossover frequency and the phase margin cannot be determined. Do you have an idea how to get htis?

    Thanks

    Fred

    Hi Fred,
    Sorry I'm not quite understand. This part is needs external compensation, first you decide the crossover frequency, and then configure the compensation circuit. Usually the phase margin needs to be larger than 45 to insure stability.

    Thanks & Best Regards
