The simple guidelines for positioning the poles and zeros and for calculating the
component values for a Type III compensation scheme are as follows:
Where ZSF=(
f
compensation double zero)/(
f
circuit double pole)
Here ZSF is set at 1.2.
As a particular example, consider for the following SP6138EB, 3A
MAX
with a type III
Voltage Loop Compensation component selections:
Vin_max = 15V
Vout = 3.30V @ 0 to 3A load
Select L = 2.2 uH => 15% current ripple.
Select Cout = 22uF Ceramic capacitors (Resr
≈
5m
)
