The spreadsheet allows to design a filter for EMI conducted for a buck converter.
See AN2162 for more details
I am trying to use the application note to arrive at Lf and Cf,Cd values for 110 Vin and 28 Vout in flyback converter config.
The Iout is 1.5A and noise level is 55dBuV. The Fsw - 110Khz.
But the AN2162 application note fails with the above design parameters.
