Instead of creating a new thread I found this one, which is what I am looking for. I am using a single MP3429 instead of the MP3431 but for my purposes they are basically the same.
ACDCguy (or other MPS engineer), if I may ask, could you clarify a little more on the Iout sense part in your suggested solution? I am a too much of a beginner to know exactly what it your solution is. The red triangle you added, is it a OP-AMP, current sense amplifier or something else? Would it be too much to ask for a more detailed schematic of your solution? And also, how would I calculate the resistor you have added above it?
I have been looking for specific LED drivers with CC regulation and boost topology but I have not found any device that comes close to the MP3429/31 output capacity. I have designed PCB around the MP3429 which works except that and am having difficulties implementing CC instead of CV. Any help will be appreciated.
Thanks in advance,
