Claim 15:
16. The control circuit of claim 13, wherein the secondary-side control signal generator comprises:
a second comparator comprising a first input, a second input and an output, the first input receiving the signal characterizing the voltage of the secondary-side winding, the second input receiving the third reference;
a second flip-flop comprising a set terminal, a reset terminal and an output, the set terminal connected to the output of the second comparator; and
a third AND gate comprising two inputs and an output, the two inputs connected respectively to the output of the second comparator and the output of the second flip-flop, and
wherein an output signal from the output of the third AND gate serves as the secondary-side transistor switch control signal.
