Cxle86100 is a high efficiency, step-down high brightness LED constant current driver chip. Built in power MOS tube, especially suitable for LED Driver with 12 ~ 85V wide input voltage range

Cxle86100 is a high efficiency, step-down high brightness LED constant current driver chip. Built in power MOS tube, especially suitable for LED Driver with 12 ~ 85V wide input voltage range. The cxle86100 adopts the peak current control mode with fixed turn off time, and its working frequency can reach up to 1MHz, which can reduce the volume of external inductance and filter capacitance, improve efficiency and save PCB area. The working frequency can be adjusted by the external RC capacitor or according to the user's requirements. Add PWM signal at en end to adjust the brightness of LED lamp. Linear dimming can be set at FB end. Cxle86100 sets the current flowing through the LED lamp by adjusting the resistance value of the external current detection resistor, so as to set the brightness of the LED lamp. The current flowing through the LED lamp can vary from tens of Ma to 850 ma
