1. A control circuit, comprising:
a control module connected between a power supply and a load; a delay module comprising a first capacitor, a variable resistor, and a first electronic switch; and a second electronic switch, wherein when a voltage supplied by the power supply is consistent with a preset value, the control module outputs a power good signal to the load, the control module outputs a control signal at the same time, a first end of the variable resistor is connected to the control module through the first capacitor to receive the control signal, a first terminal of the first electronic switch is connected to a second end of the variable resistor, a second terminal of the first electronic switch is grounded, a control terminal of the first electronic switch is connected to a general-purpose input output (GPIO) connector, the first terminal and the second terminal of the first electronic switch are connected to each other when the control terminal of the GPIO connector outputs a high level signal to the first electronic switch, a first terminal of the second electronic switch is connected to the power supply, a second terminal of the second electronic switch is connected to the load, a control terminal of the second electronic switch is connected to the control module to receive the control signal delayed by the delay module, and the first terminal and the second terminal of the second electronic switch are connected to each other when the control terminal receives the control signal delayed by the delay module. |
