IR2166SPBF

Lighting, Ballast Controllers Overview

The IR2166SPBF is a fully integrated, protected 600V ballast control IC designed to drive all types of fluorescent lamps. It combines PFC, ballast control, and half-bridge driver functions in a single chip. The device operates with critical conduction mode boost type PFC to provide high power factor and low total harmonic distortion. It features programmable preheat and run frequencies, programmable preheat time, programmable dead-time, and programmable over-current protection. Comprehensive protection includes lamp strike failure, filament failures, end-of-life protection, DC bus undervoltage reset, and an automatic restart function.

Lighting, Ballast Controllers Feature Summary

• Integrates PFC, ballast control, and half-bridge driver in one IC
• Supports critical conduction mode boost type PFC for high PF and low THD
• Features programmable preheat/run frequencies and programmable dead-time
• Includes comprehensive protection against lamp strike failure and filament failures

Lighting, Ballast Controllers Applications

• Fluorescent lamp ballast control
• PFC circuitry for lighting applications
• Half-bridge driver circuits for AC line operation

Lighting, Ballast Controllers Procurement Notes

Verify the specific suffix 'SPBF' corresponds to the 16-lead narrow body SOIC package as documented. Confirm RoHS compliance status through official datasheets or manufacturer declarations. Check current product lifecycle status, as older ballast control ICs may be subject to discontinuation or obsolescence notices. Ensure supply chain sources provide authentic Infineon components with traceable documentation.

Lighting, Ballast Controllers Selection Notes

Select this component when a single IC solution is required for driving fluorescent lamps with integrated power factor correction. It is suitable for designs needing programmable preheat and run frequencies without external complex timing circuits. Consider its 600V rating for direct AC line interfacing. Evaluate if the integrated protection features meet specific safety requirements for lamp failure scenarios.

Lighting, Ballast Controllers Part Context

The IR2166 series belongs to Infineon's family of integrated ballast control ICs. The SPBF variant specifically denotes the lead-free version in a 16-lead narrow body SOIC package. This part consolidates multiple discrete functions typically found in traditional ballast designs into a compact semiconductor solution, simplifying layout and reducing component count for lighting manufacturers.

Lighting, Ballast Controllers Replacement Considerations

Consult official Infineon documentation for direct pin-to-pin replacements or functional equivalents within the IR21xx series. Verify compatibility with existing PCB footprints and thermal management requirements when substituting.
