BD9C301FJ
4.5V~18V 입력, 3A 동기정류 1ch 강압 DC/DC 컨버터

BD9C301FJ는 저 ON 저항 파워 MOSFET를 1chip에 내장한 동기정류 강압 DC/DC 컨버터입니다.
넓은 입력전압 범위에서 동작하며, 최대 3A의 전류를 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.

    • Evaluation Board
    • BD9C301FJ-EVK-001
    • BD9C301FJ-EVK-001 Evaluation board delivers an output 3.3 volts from an input 4.5 to 18 volts using BD9C301FJ, a synchronous rectification stepdown DC/DC converter integrated circuit, with output current rating of maximum 3A. The output voltage can be set by changing the external parts of circuit and the loop-response characteristics also can be adjusted by the phase compensation circuit.
