what is the relationship between cross frequency and transient response for DC/DC?

     I am confused about the relationship between cross frequency and transient response for DC/DC faced with analysis of stability and transient response of loop control,and i 'm desired to get a theory analysis in detail.

    Hello user4664843,

    You could check out the Control Theory Seminar here:

    Another source of data could be this basic app note:

    The app notes: "Understanding ... Power Stages ..." that can be found on the TI webpage could be helpful as well.

    At the end, the higher the crossover frequency, the faster the transient response (if the converter is stable :-) )

    Best regards,
    Brigitte
