Hello!
I am working on a project that has the goal of increasing the output frequency of an LED driver from 600hz to about 10khz. It would be simple to increase the frequency in the code, as I've done it before and had the desired effect. However, I need to be able to take the output of this driver and increase its frequency while keeping the signal. This is because out cameras can pickup flicker from LEDs at an extremely high rate and I need to get up to 10khz to be safe. I think I'm kind of in the right zone as I've been trying to work with Phase-Locked Loops but have yet to create a working prototype. Heres a link to the circuit I was trying to work with, http://www.eetimes.com/document.asp?doc_id=1230513. Does anyone have any ideas on how to increase the frequency while keeping the signal? Keep in mind that it's an LED driver so this signal will be on the other end of a MOSFET.
