On looking into the spreadsheet of PI expert design tool,the following questions came up in my mind
1)In which mode does TOP 267K operate(DCM/CCM).
2)Why there is no option in spreadsheet to define the operating mode of TOP267K
3) How to arrive on the Kp value .
Can anyone help me on the above queries...
Note: I am designing a flyback converter with Optocoupled secondary regulation for a universal input power supply(85-265VAC)
