BD9P235MUF-C
Nano Pulse Control™, 3.5V～40V输入, 2A 3.3V输出, 车载一次DC/DC转换器
BD9P系列是兼顾高速响应和高效率的42V耐压车载一次DC/DC转换器IC。其特点是通过Nano Pulse Control™实现的稳定且较大的降压比、通过扩频功能实现的低EMI（低噪声）、在电池刚启动时也能稳定供电的高速响应性能，有助于降低系统功耗和降低BOM成本。 A Product Change Notice (PCN) is scheduled for this product.
包括ADAS的传感器、摄像头、雷达，以及车载信息娱乐、仪表盘、 BCM（车身控制模块）在内，适用于汽车中要求小型化、高效率化、高可靠性的应用。
While there will be no changes to electrical characteristics, certain specifications will be updated.
