Abstract
A control method of a switching circuit, a control circuit of the switching circuit and the switching circuit are provided. The control circuit includes a slope buffer and a first operational amplifier. The slope buffer receives a first voltage reference, and controls slopes of a rising edge and a falling edge to generate a second voltage reference. The first operational amplifier receives an output feedback voltage and a reference voltage, and performs an operational amplification to obtain a compensation voltage. When the first voltage reference has the falling edge, the reference voltage is coupled to the first voltage reference through a first switch, and the second voltage reference is coupled to an output voltage through a second switch. When the first voltage reference has the rising edge, the reference voltage is coupled to the second voltage reference through a third switch.
