Cxle8689 is a high efficiency, boost high brightness LED constant current driver chip. Cxle8689 sets the output current through the external resistance, and the maximum current can reach 850mA

Cxle8689 adopts the peak current control mode with fixed frequency and its working frequency is 1MHz, which can reduce the volume of external inductance and filter capacitance, improve efficiency and save PCB area. The feedback voltage of 95 MV makes the loss of RS resistor very small, so it has higher efficiency. A 2a, 100m Ω NMOS switch is built in the chip to ensure high efficiency during heavy load

Cxle8689 is a high efficiency, boost high brightness LED constant current driver chip. Cxle8689 sets the output current through the external resistance, and the maximum current can reach 850mA
