Classification: CPC H  Y | IPC H

Claim 4:
5. A method for a flyback converter, comprising:
sensing an auxiliary winding voltage of the flyback converter through a primary-side waveform analyzer during a startup of the flyback converter to determine a sensed output voltage;
cycling a power switch of the flyback converter according to primary-only feedback responsive to the sensed output voltage only during the startup of the flyback converter to regulate an output voltage of the flyback converter using the primary-only feedback;
receiving a control voltage at a primary-side controller of the flyback converter through a communication interface from a secondary-side controller of the flyback converter during a steady-state operation following the startup of the flyback converter; and
cycling the power switch of the flyback converter according to secondary-side control responsive to the control voltage during the steady-state operation to regulate the output voltage using the secondary-side control.
