6~28V, 1.2A 1ch 강압 스위칭 레귤레이터 파워 MOSFET 내장 타입 - BD9E151NUX

BD9E151NUX는 28V의 높은 입력전압에 대응하는 파워 MOSFET 내장 다이오드 정류 강압 컨버터입니다. 다이오드 정류이므로, 경부하 시에는 자동적으로 펄스를 스킵하여 고효율을 유지합니다. 또한, 셧다운 시 전원전류가 0µA로 작으므로, 배터리 구동 어플리케이션에 사용 가능합니다. 세라믹 콘덴서 사용이 가능하며, 전류 모드 제어를 통한 고속 부하 응답 및 외부 설정이 용이한 위상보상 시스템을 구비하여, 넓은 범위의 외장 정수를 통해 소형 전원을 간단히 실현할 수 있습니다.
