I have simulated it, but with an ideal inductor and I haven't put the
IRF730 model in there. Just picked a FET out of a hat. I will try to
get the right FET model to deal with the output capacitance better, then
hopefully it will be more accurate. I don't know how to get a
non-linear magnetic device modelled yet.
