Claim 8:
9. The control circuit according to claim 8, wherein the control module comprises:
a flip-flop, having an input terminal used for receiving the power supply voltage, a clock terminal used for receiving the clock signal, a reset terminal used for receiving the reset signal, and an output terminal used for outputting the logic control signal;
a seventh transistor, having a control terminal used for receiving the logic control signal, a first current terminal connected with the undershoot suppression circuit, and a second current terminal which is grounded; and
an eighth transistor, having a control terminal used for receiving the logic control signal, a first current terminal connected to the foldback current-limiting protection circuit, a second current terminal which is grounded,
wherein, the seventh transistor in turn-on state and the eighth transistor in turn-on state are used for grounding the undershoot suppression signal and the current-limiting foldback control signal, respectively.
