Constant Curent Design

Posted by: ninoub on

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.
