60V 내압 강압 동기정류 스위칭 레귤레이터 (컨트롤러) - BD9611MUV

BD9611MUV는 고전압 입력이 가능하며, 입력전압 범위 (VCC=10V~56V)가 넓은 60V 내압 강압 동기정류 DC/DC 컨트롤러입니다. PWM, 전압 모드에 의한 제어회로, 2개의 외장 Nch-FET의 구동 회로를 내장하였습니다. 발진 주파수 및 소프트 스타트의 조정 기능, 과전류 보호 (Hiccup 동작을 통한 자동 복귀형) 등의 보호 기능, 외부 CLK로의 동기 기능 등을 구비하여 자유로운 설계가 가능합니다. 또한, CTL 단자에 고정밀도 기준전압의 저입력 오동작 방지회로 (EXUVLO)가 접속되어 있으므로, VCC-GND 간 저항비를 통해 조정할 수 있습니다. 프리 바이어스에 대응하여, 기동 시 출력측으로부터의 전류 인입 (引込)을 억제합니다.
