●
Compensation network design:
–
Put the gain R5/R3 in order to obtain the desired converter bandwidth
Equation 15
–
Place
ω
Z1 before the output filter resonance ωLC;
–
Place
ω
Z2 at the output filter resonance ωLC;
–
Place
ω
P1 at the output capacitor ESR zero ωESR;
–
Place
ω
P2 at one half of the switching frequency;
–
Check the loop gain considering the error amplifier open loop gain.
