The simulation model for UCC28700 doesn't have a transformer model included. How to properly model a flyback transformer with an auxiliary winding.

Thanks

    Hi Ritwik,

    You can download UCC28600 TINA model from website This has an option to modify the parameters of the transformer - turns, Lm etc. Please copy this model for your simulation purpose.Else please feel free to use PSPICE for TI which has supports transformer modelling also. 

    Thank you

    Regards,
