Abstract
A control device of a power switch includes a discharge current generator. The discharge current generator is coupled between a control end of the power switch and a reference voltage. In a time period when the power switch is turned off, the discharge current generator combines a first current and a second current in a first sub-time period to generate a third current and sets the control end of the power switch to be discharged according to the third current. The discharge current generator merely provides the second current in a second sub-time period and sets the control end of the power switch to be discharged according to the second current. The third current is greater than the second current. The first current decreases with time in the first sub-time period. The second current is a constant current.
