Where ZSF=(f compensation double zero)/(f circuit double pole)
Here ZSF is set at 0.7.
As a particular example, consider for the following SP6133EB, 10A MAX with
component selections for a type III Voltage Loop Compensation:
Vin = 12V
Vout = 3.30V @ 0 to 10A load
Select L = 2.7 uH => 30% current ripple.
Select Cout = 200uF 2x100uF Ceramic capacitors (Resr

)
fs = 300KHz SP6133ER1 internal Oscillator Frequency
Vramp_pp = 1.0V SP6133ER1 internal Ramp Peak to Peak Amplitude
