NCL30051: PFC和半桥谐振模式离线控制器，用于LED照明

NCL30051是一款结合功率因数校正(PFC)和半桥谐振的控制器，优化用于离线LED照明应用。该器件集成实现极高能效和小型LED驱动器所需要的所有特性。它包含一个临界导通模式(CrM)升压控制器和一个半桥谐振控制器，并内置600 V高边门极驱动器。半桥段采用固定频率工作。这器件根据控制器外部生成的反馈信号，通过调节PFC段的输出电压来稳流/压，且集成了PFC反馈引脚使能输入、PFC反馈环路开路保护，和PFC过压和欠压检测机制。其它特性包括600 V启动电路，以及可以最高设定为75千赫兹(kHz)的可调节频率振荡器。内置控制器序列简化系统设计。
