IW3636-01

Overview

The iW3636-01 is a single-stage LED driver IC with integrated power factor correction, designed for wide-range dimming interfaces. It operates within an input voltage range of 90 to 305 V and supports output powers from 3 W to 90 W. The device features a switching frequency between 72 kHz and 90 kHz, achieving a power factor greater than 0.9. LED current accuracy is specified at 3%, with a dimming range spanning 1% to 100%. It includes protection mechanisms such as overvoltage, overcurrent, UVLO, and OTP, operating across a temperature range of -40°C to +85°C.

Feature Summary

• Integrates primary-side regulation technology for simplified design
• Supports multiple dimming methods including analog, PWM, and 0-10V via external controller
• Provides comprehensive protection against overvoltage, overcurrent, under-voltage lockout, and overtemperature

Applications

• Commercial solid-state lighting fixtures up to 90W
• Single-stage LED drivers requiring high power factor
• Applications supporting 0-10V dimming with iW339 controller

Procurement Notes

Verify availability status carefully, as the component may be subject to limited supply or factory special orders. Confirm the specific suffix designation matches the required dimming interface configuration. Ensure that the SOIC-8 package type and reel packaging align with production requirements. Cross-reference the manufacturer part number with official Renesas documentation to confirm current lifecycle status before finalizing procurement plans.

Selection Notes

Select this component for designs requiring a single-stage topology with integrated PFC. It is suitable for applications needing precise LED current regulation and support for various dimming protocols. Consider the thermal performance within the specified operating temperature range. Evaluate the compatibility of the primary-side regulation with the target LED load characteristics and input voltage specifications.

Part Context

The iW3636 belongs to the iW3636 series of digital offline PWM controllers for solid-state lighting. It is manufactured by Renesas Electronics Corporation, formerly Dialog Semiconductor. This series focuses on low BOM cost solutions for commercial lighting applications, offering integrated features to reduce external component count while maintaining high efficiency and reliability standards.

Replacement Considerations

Check for direct substitutes within the iW3636 series, such as the iW3636-02, which offers similar functionality with specific dimming interface variations. Verify pin compatibility and electrical parameter alignment before substitution.
