Cxle8639ea is a LED constant current driver chip which can adjust brightness / color temperature in two sections. It is suitable for 200Vac ~ 240VAC or 90vac ~ 130vac input voltage, and the constant current accuracy is less than ?4%.
When cxle8639ea is used in the two-stage brightness adjustment application, the power switch can be turned off according to the switch, and the output current can be changed in turn, so as to change the brightness of the lamp. The adjustment proportion can be adjusted through the external next resistor.
In the application of cxle8639ea in two-stage color temperature regulation, the switch state of two output ports can be changed in turn according to the power switch on and off, and the two LED lights of different colors can be turned on and off alternately to achieve the purpose of color temperature regulation
