More Information
Summary:A power driver of the present invention comprises: a level shifter unit for outputting a plurality of timing signals having different phases as square waves having first and second levels; a gate pulse modulation terminal for outputting a standard voltage having a third level; and a gate pulse modulation unit including a common switch for commonly switching the standard voltage and a plurality of individual switches respectively connected to the common switch, and transitioning the outputted timing signals by passing through the standard voltage. 본 발명에 의한 전원 드라이버는 제1 및 제2 레벨을 가지는 구형파로서 서로 다른 위상을 가지는 복수의 타이밍 신호들을 출력하는 레벨 쉬프터부 및 제3 레벨을 가지는 기준 전압을 출력하는 게이트 펄스 변조 단자, 상기 기준 전압을 공통으로 스위치하는 공통 스위치 및 상기 공통 스위치와 각각 연결된 복수의 개별 스위치들을 포함하고, 상기 기준 전압을경유하여 상기 출력된 복수의 타이밍 신호들을 천이시키는 게이트 펄스 변조부를 포함한다.
