IS31LT3935 - TRIAC Dimmable AC/DC LED Driver

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.

Key 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.

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 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.
