Abstract:
Embodiments of the present application provide a control circuit and a control method of a flyback converter, the control circuit comprises: a first sampling module, a second sampling module, and a control module; the first sampling module is coupled to the control module and the flyback converter, and outputs a first voltage signal to the control module; the second sampling module is coupled to the control module and the flyback converter, and outputs a second voltage signal to the control module; where the first voltage signal reflects an input voltage of the flyback converter, the second voltage signal reflects an output voltage of the flyback converter; the control module outputs a control signal according to the first voltage signal and the second voltage signal, and the control signal reflects a turn-on time of the switch in the flyback converter.

Claim (Index 15):
The control method according to  claim 14 , wherein,\n the turn-on time is calculated as follows: t on = 2 \ue89e t s \ue89e R \ue89e \ue89e 3 + R \ue89e \ue89e 4 R \ue89e \ue89e 4 \ue89e V O_Sense \ue89e N S N A \ue89e L P \ue89e I out * R \ue89e \ue89e 1 + R \ue89e \ue89e 2 R \ue89e \ue89e 2 \ue89e V IN_Sense wherein, t on  is the turn-on time, R 1  is a resistance value of the first resistor, R 2  is a resistance value of the second resistor, R 3  is a resistance value of the third resistor, R 4  is a resistance value of the fourth resistor, V IN _ Sense  is the first voltage signal, V O _ Sense  is the second voltage signal, N S  is the number of turns of a secondary side winding of the flyback converter, N A  is the number of turns of the auxiliary winding, L P  is an inductance of a primary side winding in the flyback converter, I* out  is the expected value of the output current of the flyback converter, and t s  is an switching cycle of the switch.
