If it is controlled by a microprocessor, you can refer to the peak current control of the UC3842/3843/3844/3845 control chip and then write it into a program.

If you want a program for a specific model, even if you get it, your ability and knowledge will not increase.

What chip can be used for analog control? Is there a chip similar to the L6561 used in CRM Boost? The peak current reference envelope is the product of the input voltage and the output compensation signal, but the turn-on signal is not zcd, but a fixed frequency turn-on.
