MOSFET 내장 1ch 강압 스위칭 레귤레이터 - BD9G341AEFJ

BD9G341AEFJ는 고전압 76V 입력에 대응하는 파워 MOSFET 내장 강압 1ch 스위칭 레귤레이터입니다. 80V 내압 3.5A 정격, ON 저항 150mΩ의 파워 MOSFET를 내장하고 있습니다. 또한, 전류 모드 제어 방식을 채용하여 고속 과도 응답을 실현하였으며, 위상보상 설정도 용이합니다. 주파수는 50kHz~750kHz까지 가변 가능하며, 저전압 오동작 방지회로, 과전류 보호회로 등 보호 기능을 내장하고 있습니다. 또한, 고정밀도 EN Pin threshold를 통해 저전압 lock out 및 히스테리시스를 외장 저항으로 설정할 수 있습니다.
