| description | The invention relates to a switching power supply control system, and provides a switching power supply control system. The switching power supply control system comprises a filtering and rectifying circuit, a control circuit and an output circuit, wherein an input end of the filtering and rectifying circuit is connected with alternating current power supply, and an output end of the filtering and rectifying circuit is connected with the control circuit; and an input end of the control circuit is connected with the output end of the filtering and rectifying circuit, and an output end of the control circuit is connected with the output circuit. In addition, the control circuit comprises a feedback voltage-dividing resistor, a sampling and holding assembly and a switch driving assembly, wherein the sampling and holding assembly is configured to obtain the sampling voltage through a voltage-dividing signal of the feedback voltage-dividing resistor and obtain the demagnetization time at least partially based on t |
