onsemi NCP1399 고성능 전류 모드 컨트롤러
onsemi NCP1399 고성능 전류 모드 컨트롤러는 하프 브리지 공진 변환기에 사용되며 600V 게이트 드라이버를 구현하여 레이아웃을 간소화하고 외부 구성 요소 수를 줄일 수 있습니다. 이 소자는 모든 애플리케이션에서 컨트롤러를 쉽게 구현할 수 있는 내장형 브라운아웃 기능을 갖추고 있습니다. NCP1399는 PFC 전단이 필요한 응용 기기에서 PFC 컨트롤러를 구동하기 위한 전용 출력부가 있습니다. 이러한 기능은 전용 스킵 모드 기술과 함께 전체 애플리케이션의 경부하 효율을 추가로 개선합니다.
