  • Hi A.P.

    Thank you for designing with the LM5163.  Sorry our serve does not allow me to download your google doc file.

    Anyway, I am not sure if your transfer of the pspice model to Simplis causes any errors.  Could you simulate with TINA, or Pspice, or Pspice for Ti?

    Thanks,

    Youhao
