R COMP and C COMP have limited effect on the crossover frequency, and are used only to fine tune the crossover frequency
and transient load response. Choose the desired crossover frequency fc1 around fc estimated by Equation (13) and
determine R COMP and C COMP.

C CP1 is optional and may be needed in some applications to reduce the jitter caused by the high frequency noise. A
ceramic capacitor between 10pF and 220pF is usually enough. In equation (14), V IN is the input voltage, F M is the PWM
comparator gain (refer to equation (22)).
Type III Compensation
Determine the compensation at no load, the worst case condition. Assume the time constant of the resistor and capacitor
across the output inductors matches that of the inductor, the crossover frequency of the voltage loop can be estimated by
Equations (16).

Choose the desired crossover frequency fc1 around fc estimated by Equation (16). Select other components to ensure the
slope of close loop gain is -20dB/Dec around the crossover frequency. Choose resistor R FB1 according to Equation (17),
and determine C FB and C DRP from Equations (18) and (19).
