LT4430 Compensation Network


I am using LT4430 in a new power supply design.

I am designing a Fixed Input-Variable Output Flyback where duty varies from 25% to 75%.

I would like to use LT4430 to drive the optocoupler but I can't figure out how I can choose components values for the compensation network.

In the datasheet there is only the transfer function. Can you please share an Application Note or something else that can help me?
