Flicker-FreeTM IS31LT3935 TRIAC Dimmable AC/DC LED Driver with Active PFC March 2013 Preliminary GENERAL DESCRIPTION The Flicker-Free™ IS31LT3935 is a single stage current-mode LED driver optimized for high power factor and patibility with all TRIAC dimmers. The PFC architecture enables excellent power factor over a wide range of operating line and load conditions, even with the simplest of inductor-based driver topologies, thereby reducing system cost and size while maximizing efficiency. The IS31LT3935 LED controller Features patent pending AccuDim™ flicker-free dimming technology that mimics the characteristics of an incandescent light bulb. It presents a dynamic impedance to the...
