Abstract:
The disclosure relates to a control circuit, a control method and a flyback converter of primary-side feedback control including the control circuit. When an input voltage is greater than a predetermined threshold, a peak value of an input current of the flyback converter is controlled to vary with the input voltage by the switching control signal. When the input voltage is less than the predetermined threshold, the peak value of the input current is controlled to be increased by the switching control signal to make demagnetization time of a secondary winding of the flyback converter be greater than a minimum time. Thus, the peak value of the primary-side current may not become too small because of a decreased input voltage, further avoiding occurrence of an error sampling after a blanking time due to excessive variations in demagnetization time.

Claim (Index 17):
The control method according to  claim 16 , wherein\n sampling a primary-side current to obtain a current sampling signal; sampling a voltage across an auxiliary winding after a blanking time to obtain a voltage sampling signal; generating a switching control signal in accordance with said voltage sampling signal; and controlling said power switch in said flyback converter in accordance with said voltage sampling signal and said current sampling signal, wherein said blanking time varies with a peak value of said current sampling signal.
