Wltr0, This is 20 questions bundled into one forum post :D, you will not be satisfied by whatever I might reply :) as the questions themselves are more consulting in nature, where you pay someone to consult you on the implementation. 1. For hysteresis control, we don't have a good example that i can point to that we have done. There is a lot more to it than what meets the eye here, what are the limits on the switching frequency on your hysteresis controller etc. I believe you have asked this question previously. 2. We currently don;t have any hysteresis based current controller design, nor a three phase PFC (we do have vienn rectifier TIDM-1000 ) but not the one you are looking at right now. Hence i cannot recommend anything on this. 2. F28069 should have enough performance to do what you are doing from a bandwidth perspective. Maybe some one from the community can help, but from TI side I am not sure how i can provide you a specific answer for such a broad question. regards Manish
