Abstract
A control circuit used in a switch mode power supply is provided. The control circuit has an error amplifier, a first compensation network having a first resistance and a second compensation network having a second resistance. The error amplifier has a first input terminal, a second input terminal and an output terminal. The first compensation network is coupled between the first input terminal and the output terminal of the error amplifier. The second compensation network is coupled to the first input terminal of the error amplifier. When the switch mode power supply enters the transient state, the control circuit increases the first resistance of the first compensation network or decreases the second resistance of the second compensation network.
