4.2V~18V 입력, 2A 동기정류 1ch 강압 DC/DC 컨버터 - BD9328EFJ-LB

본 제품은 산업기기 시장용으로, 장기간 공급을 보증하는 제품입니다.
BD9328EFJ-LB는 저 ON 저항 파워 MOSFET를 1chip에 내장한 동기정류 강압 DC/DC 컨버터입니다. 넓은 입력전압 범위에서 동작하며, 약 2A의 전류를 연속으로 출력할 수 있습니다. 적은 외장 부품으로 구성이 가능하여 비용 절감에 효과적입니다. 전류 모드 제어 DC/DC 컨버터이므로 고속 과도 응답 특성을 지니며, 위상보상 설정도 용이합니다.
ROHM 신규 채용품으로 BD9C301FJ-LB를 권장합니다.
