BD9S400MUF-C
오토모티브용 2.7V~5.5V 입력 4A MOSFET 내장 1ch 동기정류 강압 DC/DC 컨버터
BD9S400MUF-C는 저 ON 저항 파워 MOSFET를 내장한 동기정류 강압 DC/DC 컨버터입니다. 최대 4A의 전류를 출력할 수 있습니다. SLLM™ 제어로, 경부하 시에도 효율 특성이 양호하여 대기 시 전력 삭감에 최적입니다. 스위칭 주파수가 2.2MHz로 고속이므로 소형 인덕터 사용이 가능합니다. 전류 모드 제어를 통해 고속 부하 응답과 간단한 위상보상 설정을 실현합니다. 또한, 외부 펄스에 동기 가능합니다.

- CISPR25 Class5 compliant 8 rails power tree Reference Design for Automotive ADAS/Infotainment application
This reference design is a power tree solution board developed for infotainment devices such as automotive clusters and center information displays and for ECUs for ADAS application. The power system that can support functional safety is integrated on a single board to achieve the optimal configuration as a power tree. Excellent EMC performance that meets CISPR25 Class 5 even at all power supply rails are enabled, and reduces heat generation of each device by distributing high-efficiency DCDCs. In addition, two supervisor ICs with self-diagnosis functions can monitor the output of all power rails and contribute to a higher level of functional safety.
- Automotive Infotainment/ADAS 8-channels power tree reference design
- Verified to satisfy EMC CISPR 25 class 5 standard without common mode filter
- In order to avoid the AM radio frequency bands All DC/DC converters operate at a switching frequency of 2.2 MHz or higher.
- Thermal characteristics tested
- voltage monitoring for 8-channel power tree to improve the functional safety ASIL level
- Space saving by integrating multiple power trees
