  • Patent number: 10505461
    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.
