Claim 0:
1. A control circuit, comprising: control sub-circuit
a control sub-circuit;
a detection circuit, connected with a plurality of output voltage feedback terminals of a drive chip, and the detection circuit being connected with the control sub-circuit; and
a voltage regulating circuit, wherein the voltage regulating circuit comprises: a first resistor and a second resistor; a first terminal of the first resistor being connected to an external power supply, a second terminal of the second resistor being grounded, and a second terminal of the first resistor and the first terminal of the second resistor being connected for providing with the second voltage,
wherein the detection circuit is configured for providing a first voltage to the control sub-circuit when a voltage of at least one output voltage feedback terminal in the plurality of output voltage feedback terminals is detected, the first voltage being greater than a second voltage received by the control sub-circuit; and
the control sub-circuit is configured for controlling the drive chip to restart when the first voltage is greater than the second voltage.
