The minimum operationg frequency for LTC3779 is 50kHz. With 50kHz switching frequency, check with your power device vendor to see any available IGBT for your application. You might need to parallel several phase to handle such power.
For the input voltage rated below 200V, you may also consider using power MOSFET which enable you to run at higher switching frequency. However, denpendant on the current rating and thermal stress, you may parallel more phases. If you do select IGBT as the power device, you need extra IGBT gate driver and bias power supply.
For more detail support, please contact your local ADI FAE.
But 50Khz switching frequency is too high for IGBT.
So I try to use MOSFET.
