Abstract
A control circuit of a power converter includes a first sensing circuit, a reference voltage generation circuit, an error amplifying circuit and a PWM circuit. The first sensing circuit, coupled to a first output circuit, provides a first current sensing signal. The reference voltage generation circuit, coupled to the first sensing circuit, provides a reference voltage according to the first current sensing signal. The error amplifying circuit, coupled to the reference voltage generation circuit, receives the reference voltage and an output feedback voltage of the power converter to provide an error amplifying signal. The PWM circuit, coupled between the error amplifying circuit and the first output circuit, receives the error amplifying signal and provides a control signal to control the first output circuit. The reference voltage generation circuit further receives the error amplifying signal and adjusts the reference voltage it generates according to the error amplifying signal.
