IW3614-00

Overview

The iW3614-00 is an AC/DC digital power controller optimized for dimmable LED luminaires requiring high power factor. It operates from a 100V AC to 230V AC input range and supports output powers up to 25W, with specific design targets for 3W to 15W applications. The device integrates Flickerless technology to eliminate visible flicker and PrimAccurate primary-side control to remove the need for opto-isolators. It features a switching frequency of 200 kHz and includes over-temperature protection via external NTC input.

Feature Summary

• Integrates Flickerless technology to remove LED flicker and ensure stable light output
• Utilizes PrimAccurate primary-side control to minimize external component count by eliminating opto-isolators
• Supports broad dimmer compatibility including leading edge, trailing edge, and non-traditional types
• Includes over-temperature protection derating feature using external NTC monitoring

Applications

• High power factor dimmable LED drivers
