Abstract
In a synchronous rectification switching power supply circuit and a control method for a primary switching transistor and an electronic device, one end of a first switching transistor is coupled to a transformer, and the other end thereof is grounded; a second end and a third end of the transformer are respectively coupled to a first end of the first capacitor and a first end of the second switching transistor; a second end of a second switching transistor is coupled to a second end of a first capacitor; a first resistor is connected in parallel with the first capacitor; and a monitoring circuit is coupled to the switching transistor control unit in such a manner that the operating condition of the secondary side output rectification circuit is monitored in real-time by the monitoring circuit.
