Cxle8779b is a special driver chip designed for LED lighting system which provides three channels of high-precision constant current gray-scale modulation output

Cxle8779b has built-in 5V voltage stabilizing circuit, which can increase the external power supply voltage to 9V ~ 24V through external resistance. Internal integrated current gain control module, when the set port is grounded, the current value of the outr / g / B port can be adjusted through the system controller. Outr / g / B port withstand voltage + 26V or above, chip port HBM ESD reaches 8Kv, high reliability
