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 9):
A controlling method for an isolated switching converter including a transformer, the method comprising:\n a) detecting a current signal flowing through a main switch of said isolated switching converter; b) generating a blanking control signal in accordance with said current signal, and regulating a length of an effective time interval of said blanking control signal in one switching period in accordance with said current signal; c) starting to detect a voltage signal of an auxiliary winding of said transformer after said effective time interval has elapsed from a time that a main switch of said isolated switching converter is turned off; d) determining a sampling time in accordance with said detection of said voltage signal; e) configuring said voltage signal sampled at said sampling time as a detection signal representing an output voltage signal of said isolated switching converter; and f) controlling states of said main power switch in accordance with said detection signal.
