Abstract:
A flyback power converter circuit includes a transformer, a power switch, a primary side controller circuit, and a secondary side controller circuit. The transformer converts an input voltage to a first, a second and a third output voltages. The primary side controller circuit and the secondary side control are powered by the second voltage and a third voltage, respectively. In a burst mode, when the second output voltage is lower than a first threshold, a power regulation mode is triggered to control the power switch, such that the second output voltage is between the first threshold and a second threshold. After a predetermined delay time period, the power regulation mode stops and the flyback power converter circuit enters a reboot procedure, wherein the power switch is OFF such that the third voltage is lower than a secondary side reboot threshold, whereby the secondary side controller circuit is reboot.

Claim (Index 15):
A method for controlling a flyback power converter circuit, the flyback power converter circuit comprising a transformer including a primary winding configured to receive an input voltage at a primary side of the transformer, a secondary winding configured to generate a first output voltage at a secondary side of the transformer, and an auxiliary winding configured to generate a second output voltage; a secondary side controller circuit at the secondary side of the transformer, the secondary side controller circuit being powered by a third output voltage which is related to the first output voltage, and being configured to control a coupling device according to the first output voltage to provide a feedback compensation signal to the primary side of the transformer; and a power switch coupled to the primary winding; wherein the primary side controller circuit is at the primary side of the transformer, the primary side controller circuit being powered by the second output voltage, and being configured to generate a switch control signal for controlling the power switch, wherein the coupling device is coupled between the primary side controller circuit and the secondary side controller circuit, the method comprising:\n when the comparison output signal indicates that the second output voltage is lower than the first voltage threshold in a burst mode, triggering the flyback power converter circuit to enter into a power regulation mode wherein the power switch is controlled such that the second output voltage is between the first voltage threshold and the second voltage threshold; stopping operating in the power regulation mode after a predetermined period of time from entering into the power regulation mode such that the primary side controller circuit starts a reboot procedure; and in the reboot procedure, the power switch is OFF such that the third output voltage is lower than a secondary side reboot threshold to reboot the secondary side controller circuit.
