Hi Ponkamali,

Please look at the UCC28750. This should fit for what you need to do.

Thanks,

Robert

I am looking for primary side regulation and found UCC28730. Can this be used for HV applications upto 1500V in Cascode topology? The concern is gate drive current which is around 30mA for UCC28730.
