The crossover frequency of the loop is either selected to be 1/10th the switching frequency or 1/5th the right-half plane zero frequency, which ever is lower. Equation 23 shows the calculation for 1/10th the switching frequency. Equation 24 shows how to calculate the 1/5th the right half plane zero frequency.
where
The crossover frequency is selected to be 1/5th the right half plane zero frequency, 2.51 kHz.
