Designing LED driver using top switch

Posted by: zahra on

Hi,
When we use top switch for LED driver which part of circuit get feedback from output current?
I designed a LED driver with 27V and 0.5A by PI expert. I attached the schematic.

Hi zahra,
It seems that TOPSwitch does not have a built in constant current mode. You would have to add external circuitry to achieve constant current regulation. I recommend that you use our LED lighting products for your LED driver application. You can check on this link to see which of our products satisfy your needs.
