Abstract
A driver circuit for switching switch according to capacitor voltage is disclosed in the present invention. The driver circuit is provided to drive a load circuit which includes a load resistor under a continuous conduction mode (CCM). In the driver circuit, a first current module which electrically connected to the load resistor is provided to generate a variable current. A second current module which electrically connected to the first switch and the first current module is provided to generate a constant current. A processing module is electrically connected to the first capacitor, the second capacitor and a gate of the first and the second switch. The processing module is provided to conduct one of the first switch and the second switch according to a size of the variable current and the constant current, a voltage of the first capacitor, and a voltage of the second capacitor.
