The CXLE81110 is current mode control LED driver IC designed to control single switch PWM converter in a constant frequency. External current sense resistor and slope compensation resistor make it flexible for various applications. A PWM dimming input controls a duty ratio from 0% to 100% with frequency up to few kilohertz. The CXLE81110 includes hiccup protection from both short and open circuits, with automatic recovery after the fault condition is cleared
