  Grrr thyself!  Are we talking about one winding or two?  A *single*
winding flyback design to my mind generates a voltage opposite to its
input, which I would class as a very large "drop-out" (taken to be the
difference between input and output potential) indeed.

  Suffice it to say, I know what you mean, but you know what I mean.  :)
