    APPLICATIONS INFORMATION: Continued
    The goal of loop compensation is to manipulate
    loop frequency response such that its gain crosses
    over 0db at a slope of -20db/dec. The first step
    of compensation design is to pick the loop
    crossover frequency. High crossover frequency
    is desirable for fast transient response, but often
    jeopardizes the system stability. Crossover fre-
    quency should be higher than the ESR zero but
    less than 1/5 of the switching frequency. The
    ESR zero is contributed by the ESR associated
    with the output capacitors and can be deter-
    mined by:
    Z(ESR)
     =
    1
    2
    π
     C
    OUT
     R
    ESR
    The next step is to calculated the complex con-
    jugate poles contributed by the LC output filter,
    P(LC)
     =

    When the output capacitors are of a Ceramic
    Type, the SP6132CU Evaluation Board requires
    a Type III compensation circuit to give a phase
    boost of 180
    °
     in order to counteract the effects of
    an under damped resonance of the output filter
    at the double pole frequency.
