Power Factor Controllers | MC33260
概览
MC33260 是一款用于功率因数校正预转换器的控制器，可满足电子镇流器和离线功率转换应用中的国际标准要求。其设计用于驱动自由频率续流模式，也可对其进行同步，并且在任何情况下都具有非常有效的保护功能，可确保安全可靠运行。该电路还经过优化，可提供非常紧凑且经济高效的 PFC 方案。MC33260 虽然需要最少的外部部件数量，但可以控制跟踪增压运行，该创新模式可大大减小电感器和电源开关的尺寸。最终可大大降低方案系统的成本。此外，由于它能够以传统方式运行（恒定的输出电压调节电平），任何中间方案都可以轻松实施。这一灵活性使其非常适合用于应对各种应用。
