IW3629-00

Overview

The iW3629-00 is a two-stage, non-dimmable digital off-line LED driver IC designed for 90W applications. It integrates high power factor (PF) and low total harmonic distortion (THD) capabilities with low ripple output. The device operates as a standalone solution for LED lighting systems requiring efficient power conversion without dimming functionality.

Feature Summary

• Digital control architecture for precise LED regulation
• Integrated power factor correction for improved efficiency
• Non-dimmable operation optimized for constant current loads

Applications

• General solid-state lighting fixtures
• Commercial LED downlights
• Industrial high-bay lighting systems

Procurement Notes

Verify current availability status directly with Renesas Electronics or authorized distributors, as supply may be limited or subject to special order requirements. Confirm RoHS compliance and package type (Reel/Cut Tape) against specific project needs before finalizing procurement plans.

Selection Notes

Select this component for designs requiring a non-dimmable, high-efficiency LED driver with integrated PFC. Ensure the application does not require dimming compatibility, as the device is specified for non-dimmable operation only. Validate thermal management requirements for the target power level.

Part Context
