Cxle8631 is a dual channel progressive LED constant current drive control chip. The chip uses the constant current setting and control technology patented by our company. The output current is set to 5mA ~ 60mA from the external rext resistor, and the output current does not change with the chip out port voltage, so it has better constant current performance. It can adapt to a wide range of input voltage (?20%), simple system structure, few peripheral components and low cost.
