Abstract: 본 발명은 발광다이오드 구동 회로 및 구동 방법에 관한 것으로, 정전류원을 이용하여 발광다이오드를 구동시키는 과정에서 발생되는 전력 낭비를 최소화하기 위한 것이다. 본 발명에 따르면, 전원 공급 회로는 복수의 발광다이오드에 출력전압을 공급한다. 정전류원 회로는 특정 바이어스 전류 값을 이용하여 상기 부하 트랜지스터의 게이트를 제어함으로써 부하 트랜지스터의 드레인-소스 전류를 정전류값으로 복수의 발광다이오드에 입력하여 구동시킨다. 오차증폭기는 상기 부하 트랜지스터의 드레인-소스 전압과 기준 전압의 차이에 비례하는 전압 값을 출력한다. 그리고 오차증폭기의 출력 전압 값을 이용하여 펄스폭 변조 신호를 만들고 이러한 펄스폭 변조 신호를 이용하여 전원 공급 회로의 출력전압을 제어한다. 이때 오차증폭기는 부하 트랜지스터의 드레인-소스 전압을 전원 공급 회로로 피드백시켜 부하 트랜지스터가 포화영역에서 동작할 수 있는 최소 드레인-소스 전압이 부하 트랜지스터에 인가되도록 전원 공급 회로의 출력전압을 제어한다.
