CYT8000D switching dimming / toning constant current LED IC chip
General Description
CYT8000D is a switching dimming / toning constant current LED IC chip. It’s suitable for AC 180V-240V or AC 90V-130V input voltage, constant precision< ± 5%.
When the CYT8000D is used to 3 channel dimming, the output current can be changed by turning on / off power supply, thus changing the brightness of LED. The dimming ratio can be set through external CS resistors.
When the CYT8000D is used to 3 channel color temperature adjustment, the current of two output port can be changed by turing on / off power supply to achieve the LED lamp bead light on / out alternately of two different color LED , and then achieve the function of adjusting color temperature. The output power can be set through external CS resistors.
Simple overall design structure, with over-temperature and over voltage protection function, no transformer and electrolytic capacitance, fully SMT processing and automatic operation can be realized with only a few ponents on the periphery of the drive scheme.
