Abstract

The present disclosure relates to a switching converter and its control circuit. The control circuit includes an error amplifier, a transient-response compensation circuit and a PWM comparator. The transient-response compensation circuit is coupled to an output terminal of the error amplifier for increasing a differential current of the error amplifier to increase the rate of output change of the error amplifier in a case that a voltage difference between the first feedback signal and the reference voltage exceeds a predetermined threshold. The output voltage can be prevented from having too high or too low fluctuations when a load changes, thereby improving transient response characteristics of the power converter, and optimizing dynamic characteristics of the power converter over a wide range of the fluctuation of the load in a continuous operation mode.
