Cxle8790s is a single channel LED constant current drive control chip. The chip uses the constant current setting and control technology patented by our company. The default value of the internal output current is 19.5ma, or the external rwxt resistance can be set to 19.5ma ~ 150mA, and the output current does not change with the chip out voltage and ambient temperature. Dimport can input PWM signal to realize dimming function. The system has simple structure, few peripheral components and low cost scheme
