Abstract
Disclosed is a switching converter without an auxiliary winding. The switching converter has a transformer, a switching transistor, a coupling circuit and a regulating circuit. The transformer has a primary winding and a secondary winding, and is for transforming an input voltage into an output voltage; a first end of the switching transistor is coupled to the primary winding of the transformer, and the switching transistor is for controlling an operation of the transformer according to a control signal; the coupling circuit is for coupling a signal at the first end of the switching transistor to generate a coupled signal; and the regulating circuit is for detecting the coupled signal to generate the control signal according to the detecting result.
