IW3636-02

Overview

The iW3636-02 is a single-stage LED driver IC with integrated power factor correction, designed for solid-state lighting applications up to 90W. It operates within an optimal input voltage range of 90V to 305V and features a switching frequency between 72kHz and 90kHz. The device supports analog, PWM, and 0-10V dimming (with iW339), achieving a dimming range from 1% to 100%. Key electrical specifications include LED current accuracy of 3%, output power ranging from 3W to 90W, and a power factor greater than 0.9. It utilizes PrimAccurate technology and includes protection features such as OVP, OCP, UVLO, and OTP.

Feature Summary

• Integrates PrimAccurate technology for precise primary-side regulation without secondary sensing components.
• Supports multiple dimming interfaces including calibrated DIM1, NTC DIM2, analog, PWM, and 0-10V via external controller.
• Provides comprehensive protection mechanisms including over-voltage, over-current, under-voltage lockout, and over-temperature protection.

Applications

• Commercial solid-state lighting fixtures
• LED drivers requiring low bill-of-materials cost
• Single-stage AC/DC conversion systems

Procurement Notes

Verify availability status carefully as the component may be subject to limited supply or factory special orders. Confirm package type (SOIC-8) and reel quantity requirements against specific project needs. Ensure compatibility with required dimming interfaces, particularly if utilizing 0-10V control which necessitates the iW339 interface chip. Cross-reference manufacturer part numbers to avoid confusion with similar series variants.

Selection Notes

Select this component for designs prioritizing reduced component count through single-stage topology. It is suitable for applications requiring wide input voltage ranges and high power factor performance. Consider the need for external dimming controllers like the iW339 for specific analog or 0-10V protocols. Evaluate thermal management requirements given the operating temperature range and power levels involved in commercial lighting implementations.
