Cxle8691 is a high efficiency, boost high brightness LED constant current driver chip. Five functions are integrated inside: full light, half light, micro light, explosion flash and SOS

The mode switching among the five functions can be realized through the on-off of the power switch. No additional MCU or other control IC is required. Cxle8691 sets the output current through the external resistance, and the maximum current can reach 750ma. Cxle8691 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. 95 MV feedback voltage 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
