hello
can anyone suggest me how to control quasi resonant buck. I had designed the power stage for 2MHz switching operation (resonant freq is 2.7 MHz). In my feedback loop i am using VCO and Eamp with type 3 compensation. I had reffered ON semiconductors appl.nte for the compensator design.
The problem is my output is settling at required voltage but with high noise and more settling time. How to tune the compensator for fine performance.

Specifications: Vin=24V, Vout=3.3V, Ripple in Vout=1%, Iout=10%. Load from 10A to 6A.

Thanks in advance
