IW3671-00C

Overview

The IW3671-00C is a single-stage, high power factor (PF), low total harmonic distortion (THD) AC/DC controller designed for LED lighting applications up to 100W. It supports both constant-voltage and constant-current output modes. The device integrates primary-side regulation capabilities to minimize external component count. Key electrical characteristics include an operating frequency range and specific current sensing thresholds defined in the official datasheet. It utilizes a Reel or Cut Tape packaging format suitable for automated assembly processes.

Feature Summary

• Single-stage topology integration for simplified design
• High power factor and low THD performance compliance
• Primary-side regulation capability reducing component count
• Support for constant-voltage and constant-current LED loads

Applications

• LED downlights
• LED panel lights
• Commercial linear lighting systems

Procurement Notes

Verify availability status directly with authorized distributors as supply may be limited or subject to factory special orders. Confirm RoHS compliance details through official documentation before finalizing procurement plans. Ensure ordering suffixes match exact package requirements such as Reel or Cut Tape configurations specified by the manufacturer.

Selection Notes

Evaluate thermal management requirements based on the intended power level up to 100W. Consider PCB layout constraints for primary-side regulation accuracy. Verify input voltage ranges align with regional grid standards. Assess system efficiency targets against the controller's inherent switching losses and conduction characteristics documented in technical specifications.

Part Context

This component belongs to the iW3671 series of LED lighting driver ICs manufactured by Renesas Electronics. It serves as a specialized solution for efficient AC-to-DC conversion in solid-state lighting. The series focuses on achieving regulatory compliance for electromagnetic interference and power quality while maintaining cost-effective bill-of-materials structures for mass production environments.

Replacement Considerations

Consult official cross-reference lists for verified substitute part numbers. Ensure functional compatibility regarding pinout, control logic, and electrical ratings when considering alternatives from the same product family or competing manufacturers.
