Classification: CPC H  Y | IPC H

Claim 5:
6. The control circuit of claim 2, wherein the secondary-side transistor switch control signal is a pulse signal, and wherein the anti-shoot-through logic circuit comprises:
a first latch configured to receive and latch the secondary-side transistor switch control signal and output a latched signal; and
a first logic gate configured to receive both the primary-side original turn-on signal and the latched signal and, if the primary-side original turn-on signal indicates to turn on the primary-side transistor switch and the latched signal indicates the arrival of the turn-off instant of the secondary-side synchronous rectification transistor, output a turn-on instant signal of the primary-side transistor switch indicating the arrival of the turn-on instant for the primary-side transistor switch.
