LYTSwitch-4

产品特色

  • 恒流(CC)调整率要优于+/-5%
  • 适用于低输入电压应用的功率因数校正(PFC)技术
  • 可控硅调光与非调光选项

说明

高性能,内部集成了驱���电路、控制电路及开关管

LYTSwitch-4产品系列可设计具备高功率因数的离线式LED驱动器,使其轻松满足国际标准规定的THD及谐波要求。输出电流经过严格调整可达到优于±5%的恒流精度1。在典型应用中,效率可轻松达到92%以上。

支持各种类型的可控硅调光器

LYTSwitch-4产品系列可以为前沿及后沿可控硅调光应用提供出色的导通(上电)性能。这会使驱动器具有更宽的调光范围以及更快的启动速度,即使在低导通角下上电时也一样出色。此外,它还具有大调光比与低“点亮”启动电流。

低方案成本与长使用寿命

LYTSwitch-4 IC具有高集成度,采用初级侧控制技术,可省去光隔离器和减少元件数。这样就可以使用低成本的单面印刷电路板。将PFC和CC功能同时集成到单级中还有助于降低成本和提高效率。132 kHz的开关频率允许使用较小的低成本磁芯。

采用LYTSwitch-4系列器件的LED驱动器无需使用初级侧大容量铝电解电容。这意味着驱动器的使用寿命可以得到大幅延长,对于灯泡和其他高温应用尤为显著。

其他特色
