IW3688-20

Overview

The iW3688-20 is an AC/DC advanced digital power controller designed for single-stage dimmable LED drivers. It integrates a high-voltage startup circuit and supports primary-side regulation to eliminate the need for optocouplers. The device features multi-mode control to optimize efficiency, audio noise, and standby power across all load conditions. It enables smooth, flicker-free dimming with wide ranges suitable for residential and commercial applications.

Feature Summary

• Integrates patented multi-mode control to dynamically optimize efficiency, audio noise, and standby power under varying load conditions.
• Enables primary-side regulation without requiring optocouplers or secondary feedback components, simplifying design and reducing bill of materials cost.
• Supports smooth, flicker-free dimming capabilities suitable for both residential phase-cut and commercial dimming systems.

Applications

• Single-stage dimmable LED lighting drivers
• Residential lighting fixtures requiring phase-cut dimming compatibility
• Commercial lighting systems requiring precise light control
