The channel current IL, flowing through the inductor, passes through the inductor.
A simple R-C network across the inductor (R1 and C) extracts the DCR Equation 4.
If There is R2:
value of ripple current flowing through the input capacitor is described as:
multiphase, the input capacitor is described as:
If an input capacitor’s rated ripple current is Ic, then the total sum of the input
value defined in Equation 9:
The output voltage as a function of load current is derived by combining Equation 9 with Equation 10:
Then：
Type II compensation network:
