深圳市怡能科技原厂代理供应IWATT系列ＩＣ，IW1692 IW3610 IW3612 IW3620 IW3614 IW1710等，全部原装正品！！

采用AC-DC数字PWM控制器，可支持前切相、后切相多种类型的调光器，专用于取代白炽灯的隔离式和非隔离式新型LED灯具（包括有空间限制的GU10和稍大的PAR（A，PAR）类型）的设计。其特点是寿命长、效率高、进一步缩小产品尺寸、降低成本、实现无闪烁调光，兼容现有各种类型的调光器。新一代IC的引脚与上一代产品iW3610保持一致，可兼容更多型号的调光器。值得一提的是，新一代IC支持热插拔，用户可在不断电时实现LED插拔而不会损坏LED模组。
在做调光驱动设计时,先根据输入电压选取起动电阻和加速起动电路阻值;选取BLEEDER电阻;选取PFC电感;变压器设计,MOSFET和输出整流管选择;I SENSE 和V SENSE选取;Bulk电容Vcc电容及noise旁路电容选择;必要的EMI FILTER电路等.
