IR2166PBF

Lighting, Ballast Controllers Overview

The IR2166PBF 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 component. The device operates the PFC circuit in critical conduction mode to ensure high power factor and low total harmonic distortion while regulating the DC bus. It features programmable preheat and run frequencies, preheat time, dead time, over-current protection, and end-of-life protection. Comprehensive safety mechanisms include lamp strike failure protection, filament failure detection, DC bus undervoltage reset, and latch immunity.

Lighting, Ballast Controllers Feature Summary

• Integrates PFC controller, ballast control logic, and half-bridge driver for fluorescent lamp applications
• Supports critical conduction mode boost PFC without requiring a current sense resistor
• Includes programmable parameters for preheat frequency, run frequency, preheat duration, and dead time
• Provides comprehensive protection against lamp strike failures, filament faults, and end-of-life conditions

Lighting, Ballast Controllers Applications

• Fluorescent lamp ballast systems
• Power factor correction circuits for lighting
• Half-bridge driver implementations for discharge lamps

Lighting, Ballast Controllers Procurement Notes

Verify the specific suffix 'PBF' indicates lead-free compliance when sourcing replacements. Confirm package compatibility with the 16-lead narrow body SOIC footprint required by the design. Ensure the target application aligns with the component's 600V rating and fluorescent lamp driving capabilities. Cross-reference manufacturer documentation for any obsolescence notices or recommended design updates.

Lighting, Ballast Controllers Selection Notes

Select this component for designs requiring a single-chip solution for fluorescent lamp control and PFC. It is suitable for applications needing programmable preheat sequences and robust fault protection. Consider the 16-lead SOIC package constraints during PCB layout. Evaluate if the integrated half-bridge driver meets the gate drive requirements for the external MOSFETs in the target circuit topology.

Lighting, Ballast Controllers Part Context

The IR2166 belongs to Infineon's family of integrated ballast control ICs. It is specifically engineered for fluorescent lighting applications where high efficiency and reliability are required. The device simplifies system design by combining multiple control functions into one package, reducing component count and board space compared to discrete solutions.

Lighting, Ballast Controllers Replacement Considerations

Check for direct pin-compatible alternatives within the same product family that offer updated packaging or enhanced protection features. Verify that any substitute maintains the 600V rating and critical conduction mode PFC capability.
