IR2166S

Lighting, Ballast Controllers Overview

The IR2166S is a PFC ballast control IC with an integrated half-bridge driver, designed for fluorescent lighting applications. It features programmable operating frequencies and comprehensive protection mechanisms to ensure reliable lamp operation. This component serves as the core controller for electronic ballasts, managing power factor correction and lamp ignition sequences.

Lighting, Ballast Controllers Feature Summary

• Integrated half-bridge driver for direct gate drive of power switches
• Programmable frequency control for flexible ballast design
• Built-in protection circuits for enhanced system reliability

Lighting, Ballast Controllers Applications

• Fluorescent lamp ballast systems
• Power factor correction circuits in lighting
• Electronic ballast evaluation and development

Lighting, Ballast Controllers Procurement Notes

Verify the specific suffix (e.g., SPBF) against the official Infineon datasheet to confirm package type and RoHS compliance. Confirm that the part status is active for new designs, as availability may vary by region and distributor. Ensure compatibility with existing board layouts when sourcing replacements.

Lighting, Ballast Controllers Selection Notes

Select this IC for applications requiring integrated PFC and ballast control in a single package. Consider the programmable frequency range and protection features when designing for specific lamp types. Evaluate thermal performance and layout requirements based on the half-bridge driver capabilities.

Lighting, Ballast Controllers Part Context

The IR2166S belongs to Infineon's family of lighting and ballast controllers. It is often associated with evaluation boards like the IRPLLNR7, which are used for testing IRS2166-based designs. The component is distinct from general-purpose gate drivers due to its specialized lighting control algorithms.

Lighting, Ballast Controllers Replacement Considerations

Check for pin-compatible alternatives within the IR2166 series or newer generations from Infineon. Verify that any substitute maintains the same voltage ratings and protection features. Consult official cross-reference lists for approved replacements.
