Abstract:
A flyback power converter includes a transformer having a primary winding receiving an input power, a secondary winding generating an output power, and an auxiliary winding generating an auxiliary voltage and providing a supply voltage, a primary side switch controlling the primary winding, a start-up switch coupled to the input voltage and the supply voltage, and a primary side controller supplied by the supply voltage. The primary side controller includes a shared pin coupled to a control terminal of the start-up switch, a start-up circuit for controlling the start-up switch to be conductive through the shared pin when the supply voltage is lower than a threshold, and a signal processing circuit receiving an auxiliary signal related to the auxiliary voltage through the shared pin and operating the flyback power converter accordingly, wherein the shared pin, besides providing a function of controlling the start-up switch, provides another function.

Claim (Index 3):
The flyback power converter circuit of  claim 1 , wherein when the controller supply voltage exceeds the start-up voltage threshold, the signal processing circuit performs at least one of the following operations according to the auxiliary sensing signal:\n (1) sensing the input voltage, (2) sensing the output voltage, (3) regulating the output voltage by feedback control, (4) compensating an output impedance of the flyback power converter circuit, (5) determining an operation mode, and/or (6) determining a conduction time of a secondary side diode.
