Flicker-Free

TRIAC Dimmable AC/DC LED Driver with Active PFC

GENERAL DESCRIPTION

The Flicker-Free™ IS31LT3935 is a single stage

current-mode LED driver optimized for high power

factor and compatibility 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 dimmer

and integrates an active bleed circuit for true dimming

performance across all dimmers.

The device is available in a tiny 10 lead DFN-EP (3mm

× 3mm) package. It operates over the temperature

range of -40°C to +85°C.
