4.5V~18V 입력, 3A 동기정류 1ch 강압 스위칭 레귤레이터 - BD95835EFJ

BD95835EFJ는 입력전압 범위 (4.5V~18V)에서 출력전압 (0.9V~VIN×0.6)을 대전류 출력으로 실현 가능한 1ch 강압 스위칭 레귤레이터입니다. 스위칭 트랜지스터용 N-MOSFET를 내장함으로써, 스페이스 절약과 동시에 고효율 동기정류 스위칭 레귤레이터를 실현할 수 있습니다. 고정 온 타임 제어 모드를 채용하여, 고속 과도 응답 특성을 실현할 수 있습니다. 가변 소프트 스타트 기능, 출력 단락 / 과전압 보호 기능을 내장하여 디지털 AV 기기용 전원으로 최적입니다.
