IW3681-10

Overview

The iW3681-10 is an LED lighting driver IC and AC/DC digital power controller designed for single-stage, high power factor, dimmable LED drivers. Manufactured by Renesas Electronics Corporation under the iW3681 series, this component integrates primary-side control to eliminate the need for optocouplers, thereby reducing bill of materials cost. It supports constant current (CC), constant voltage (CV), and constant power (CP) configurations. The device utilizes patented multi-mode control to dynamically optimize efficiency, audio noise, and standby power across all load conditions.

Feature Summary

Patented multi-mode control architecture that dynamically optimizes efficiency, audio noise, and standby power consumption across varying load conditions.
Primary-side regulation capability that removes the requirement for optocouplers and associated feedback components, simplifying circuit design.
Supports smooth, flicker-free dimming with a wide range suitable for residential phase-cut applications and commercial systems.
Integrated digital power controller functionality enabling high power factor correction in single-stage topologies.

Applications

Single-stage high power factor dimmable LED drivers
Residential phase-cut dimmable lighting solutions
Commercial lighting systems requiring precise light control

Procurement Notes

Verify current availability status as supply may be limited or subject to factory special orders. Confirm RoHS compliance details through official documentation before integration. Ensure ordering suffixes match specific package requirements such as reel or cut tape formats. Cross-reference part numbers with manufacturer databases to confirm active status and lifecycle stage.

Selection Notes

Select this component for designs requiring high power factor correction without secondary-side feedback loops. Ideal for applications prioritizing low BOM cost through optocoupler elimination. Suitable for both residential and commercial LED lighting where dimming performance and efficiency are critical. Verify thermal management requirements based on specific power levels.
