Abstract

본 발명은 티브이에 있어서 스탠바이시 스탠바이 공급전원을 선택제어하여 스탠바이시 소비되는 전력을 최소화 하고자한 초절전 스탠바이회로에 관한 것으로서 이러한 본 발명의 목적은 정전압부(5)로 부터 출력된 전압을 시정수(R2·C1)만큼 지연시켜 출력하는 전압지연수단과, 상기 전압지연수단으로 부터 출력된 전압을 그에 상응하는 디지탈 신호로 변환하는 아날로그/디지탈변환수단과, 상기아날로그/디지탈 변환수단으로 부터 출력된 신호와 설정된 기준전압(Vref1, Vref2)을 비교하고 그 결과값로 스탠바이회로 전체동작을 제어하는 마이콤과, 상기 마이콤으로 부터 출력된 제어신호에 의해 스위칭되어 대기전원을 공급 및 차단하는 대기전원공급 및 차단수단을 구비함으로써 달성되어 진다.The present invention relates to an ultra-low-power standby circuit which attempts to minimize standby power consumption by selecting and controlling a standby standby power supply in a TV. An object of the present invention is to provide a time constant for outputting a voltage output from the constant voltage unit 5. Voltage delay means for delaying and outputting by R2 · C1), analog / digital conversion means for converting the voltage output from the voltage delay means into a corresponding digital signal, and the signal output from the analog / digital conversion means. Compared with the set reference voltages (Vref1, Vref2) and the resulting value to control the overall operation of the standby circuit, and the standby power supply and shut-off that is switched by the control signal output from the micom to supply and cut off standby power It is achieved by providing means.
