Adding more leds to existing design
I changed my PI password, just in case it was something on my end that was causing the spam.
RE previous messages, Am I just expecting too much from the driver? Have I reached the limit of what it can put out? All I want now, is 2 strings of 9 leds, 330mA total current, approx. 24-27V, but I need constant current drive. Do I need to go up to a 3.3mH inductor possibly? Is the noise on the FB pin causing the issue? I put a cap with a higher voltage rating on the Cfb, and it got rid of the flashing with 16 leds, but now I need to go up to 18 to get the lumen output we need. As soon as I add them, the flashing starts again. I can't change the driver circuit alot, as our customer doesn't want a whole new design. I figure the design is around 8.3W, is this too high? I'm still thinking it is the FB that is doing it, but I need a way to get rid of that noise, I'm thinking it is from the switching diode. Any kind of RC snubber I could put on it?
Any other info I can get from the circuit that will help you? Please let me know. Any more help would be greatly appreciated. Thanks.
