On Semi NCL30001 60W(100V 450mA)离线LED驱动器解决方案
On Semi公司的NCL30001是能实现PFC和隔离AC/DC降压电源转换的高度集成控制器,非常适合功率在40W-150W间的LED驱动器电源. NCL30001可配置成恒流驱动或固定输出驱动,可调整工作频率20 kHz 到250 kHz,主要用于LED街灯照明,大功率LED驱动器和建筑物LED照明.本文介绍了NCL30001主要特性,方框图,典型应用电路以及高PFC的100V/450mA离线LED驱动器指标和电路图.
The NCL30001 is a highly integrated controller for implementing power factor correction (PFC) and isolated step down ac−dc power conversion in a single stage, resulting in a lower cost and reduced part count solution. This controller is ideal for LED Driver power supplies with power requirements between 40 W and 150 W. The single stage is based on the flyback converter and it is designed to operate in continuous conduction (CCM).
