Constant Curent Design

Dear Madam/Sir
I use the PI Expert Software to design a LED driver with Tiny Switch-III, and with constant current characteristic (as you can see in the attached photo). I attached the result structure. My problem is how it is a constant current topology while its feedback is voltage not current?
Please guide me.
Thank you

hi there, currently PIExpert 8 does not support constant current design. This is under development. However, you can use LYTSwitch, LNK-PH or LNK-PL for your design requirment. Thanks.
