Cxle86125 is a constant current driver chip of boost led. The input voltage range can be from 4.5V to 24V. Under 12V input, it can drive up to 7 1 watt LEDs. Cxle86125 uses current control method to drive LED, sets LED current through a sampling resistor, and the sampling voltage is as low as 200mV to reduce system loss and improve system efficiency. The chip detects and controls the output voltage through ov pin to protect the whole system in open circuit. Cxle86125 has built-in undervoltage protection, current limiting protection, over temperature protection and other functions to ensure that the chip and system will not be damaged under overload conditions
