摘要： The present invention provides a power supply device which includes an input unit which receives AC power, a control unit which includes a control integrated circuit to output a switching signal according to a control signal and a switching element which selectively outputs the output of the input unit by the switching signal, a transformer unit which generates a reference voltage by transforming the output of the control unit, and a power saving unit which performs the burst operation of the control integrated circuit according to a dimming signal from the outside. Therefore, while using a flyback power supply device using a power factor compensator, a response speed is secured by a pre-output unit and standby time is reduced by blocking the pre-output unit in a normal operation. Also, when a dimming signal has a low level, power is reduced in a standby mode by the burst operation of the power factor compensator by corresponding to the dimming signal with the low level.

摘要： The present invention relates to a multi-voltage input buffer and, more specifically, to an input buffer operated by multi-voltage. The input buffer comprises a first stage and a second stage. The first stage is composed of a semiconductor circuit device for first power voltage and generates a first output signal in response to an input signal by receiving variable voltage which is higher than the first power voltage as operation voltage. The second stage is composed of the semiconductor circuit device for the first power voltage and outputs a second output signal as input buffering output in response to the first output signal by receiving the first power voltage as the operation voltage. The variable voltage is a level selected from among multiple levels which are predetermined according to the level of the first state voltage of the input signal. The multi-voltage input buffer of the present invention is stable when a high input signal is applied and can secure a noise margin.
