Abstract:
A control circuit can include: a blanking time control circuit configured to generate a blanking control signal according to a peak current of a main switch of a power stage circuit of a flyback converter; a sampling time control circuit configured to generate a sampling time control signal according to the blanking control signal and a feedback voltage signal; and a voltage detection circuit configured to receive the feedback voltage signal and the sampling time control signal, and to determine the time of detecting the feedback voltage signal according to the sampling time control signal to obtain a detection signal for controlling the main switch, where the voltage detection circuit stops detecting the feedback voltage signal when the blanking control signal is active, and the period during which the blanking control signal is active is adjustable along with the peak current.

Claim (Index 3):
The control circuit of  claim 2 , wherein:\n a) said blanking circuit comprises a first resistor and a first switch coupled in parallel to said first resistor, said first resistor having a first terminal for receiving said feedback voltage signal, and a second terminal coupled to said holding circuit, wherein said first switch is controlled by said blanking control signal; b) said holding circuit comprises a first capacitor having a first terminal coupled to a second terminal of said first resistor, and a second terminal that is grounded, wherein a voltage across said first capacitor is configured as said holding signal, and said first resistor and said first capacitor form said delay circuit; c) said voltage difference circuit comprises a first voltage source having a negative pole for receiving said feedback voltage signal, and a positive pole coupled to said first comparison circuit; and d) said comparison circuit comprises a first comparator having a non-inverting input for receiving said holding signal, and an inverting input for receiving said first voltage signal, wherein said sampling time control signal is activated when said holding signal is greater than said first voltage signal.
