Claim 9:
10. An integrated circuit (IC) comprising:
a switching controller configured to receive an output voltage from an output stage of a power supply circuit and to generate a first input switching signal and a second input switching signal based on the output voltage, the first and second input switching signals provided to a first input switch and a second input switch, respectively, of an input stage of the power supply circuit, the input stage coupled to the output stage through a transformer, the switching controller also configured to generate a first output switching signal and a second output switching signal that are provided to a first output switch and a second output switch, respectively, of the output stage of the power supply circuit based on the output voltage, and the switching controller further configured to generate a clamp switching signal that is provided to an active clamping circuit of the output stage, the active clamping circuit having a clamping switch configured to close during an activation dead-time between closing the first input switch and closing the second input switch responsive to the clamp switching signal.
