Claim 6:
7. The control circuit of claim 6, wherein the primary-side control signal generator further comprises:
a first flip-flop comprising a set terminal, a reset terminal and an output, the set terminal configured to receive the turn-on instant signal of the primary-side transistor switch, the output configured to output the primary-side transistor switch control signal to the first latch so as to reset the first latch based on the turn-on instant for the primary-side transistor switch; and
a primary-side on-time timer comprising an output connected to the reset terminal of the first flip-flop, the primary-side on-time timer configured to start a timer based on the turn-on instant for the primary-side transistor switch and, after a predetermined time, output a reset signal to the reset terminal of the first flip-flop.
