产品概述 返回TOP
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. The CXLE81110 is available in a SOP-16 package
