Hello, Mr.
I was trying to develp a converter with this PFC controller;(with I/P:110AC and O/P 390DC.) when i was tuning input current(not so smooth, but it worked); found this UCC28070, on phase duty cycle is nearly 0.5, so two phase would overlap sometimes when i increased DC load.
could anyone konw how to solve this problem? thanks!
