Abstract
An exemplary embodiment of the present invention relates to a switch controller, a method for controlling a switch, and a power supply including the switch controller. According to the exemplary embodiment of the present invention, an AC input passed through a dimmer is rectified such that an input voltage is generated, and the input voltage is transmitted to the power switch. A charging current is generated using a voltage that depends on the input voltage, a zero cross-point at which the input voltage becomes zero voltage is detected using a detection voltage output from a current source, and a reference signal synchronized at the detected zero cross-point is generated.
