Hi , i need to help .I want to do an dc/dc converter 25-40V to 400V .I think to use UC3825 to control an full bridge + transformer 1:20 with e401028 (4/80sp).I don't have some good result ...Someone suggest me to use UC3875 .Can you help ?
Can you provide me some application notes for this particular. like design calculation for Interleaved flyback of this UCC28221.
Because in TI, the application note is for Forward Converter.
I don't have nothing like that in my "Kook Book". Maybe somebody from TI member can help you. To encourage you Flyback is very similar to Boost converter and good applcation notes for interleaved boost is LM5032. (App.Notes 1820).only you have to respect major difference between this two topologies.
