The invention provides a control circuit and a control method of a power supply module, the power supply module and electronic equipment. The power supply module comprises a voltage conversion circuit, a secondary side feedback circuit and an isolation circuit. The voltage conversion circuit is used for converting a DC input voltage into a DC output voltage. The secondary side feedback circuit is used for obtaining the direct-current output voltage and outputting sampling voltage according to the direct-current output voltage. The isolation circuit is used for outputting a feedback signal in response to the sampling voltage. The control circuit is used for outputting an open-loop control signal to the voltage conversion circuit in response to the situation that the feedback signal is not received; and stopping outputting the open-loop control signal in response to the condition that the open-loop wave sending information meets a preset condition. Wherein the open-loop wave transmitting ...
