When cxle8638p is used in three-stage dimming and color matching, the switch state of two output ports can be changed in turn according to the power switch on and off to realize the adjustment of output brightness and color temperature. The output power can be adjusted by adjusting the external CS resistance.
The chip uses the constant current setting and control technology patented by our company. The output current is set by the external CS resistor. The controller can realize the high-power constant current scheme design by pushing MOS and other power devices.
It is mainly used in LED lighting, architectural lighting engineering, LED landscape lighting and other fields, with simple system structure, few peripheral components and low cost.
