Abstract
The present invention relates to a converter, a switch controller controlling the switching operation of a power switch in the converter, and a switch control method. An exemplary embodiment of the present invention generates a reference current corresponding to an output current of the converter and generates a control voltage that depends on the reference current. The exemplary embodiment controls an increase or a decrease of the control voltage and determines a switching frequency of the power switch according to the control voltage. The exemplary embodiment controls the on-time of the power switch by using a reference voltage determined according to a control current that depends on the reference current.
