    摘要: Disclosed are a feedback circuit and a power supply device including the same. The power supply device converts input voltage into output voltage suitable for load condition according to a switching operation of a power switch. The feedback circuit includes a first diode connected to a first sensing voltage corresponding to output voltage and a second diode connected to the output voltage. The feedback circuit generates feedback voltage by using voltage passing through a conducted diode of the first and the second diodes. The power supply device controls a switching operation of the power switch depending on the feedback voltage.

    摘要: 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.
