Abstract:
A controller applied to a power converter includes a control signal generation circuit and a gate control signal generation circuit. The control signal generation circuit is used for generating a control signal when an input voltage inputted to the power converter is greater than a predetermined voltage. The gate control signal generation circuit is coupled to the control signal generation circuit. When the gate control signal generation circuit receives the control signal, the gate control signal generation circuit generates a gate control signal corresponding to a continuous conduction mode of the power converter to a power switch of the power converter, and the power switch is turned on and turned off according to the gate control signal.
