Hello,
I am trying to do an AC Analysis on the Error amplifier of an opto isolated Flyback SMPS (Vout=30V).
However, the gain and phase plots are garbage, do you know what I am doing wrong?
Please find attached the Error amplifier AC analysis schematic, the flyback schematic, and the AC Analysis simulation in LTspice.
(also the TL431 .sub file and .asy file also attached)
