IR2166

Lighting, Ballast Controllers Overview

The IR2166 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 PFC circuitry operates in critical conduction mode to provide high power factor, low total harmonic distortion, and DC bus regulation. Key features include programmable preheat and run frequencies, programmable preheat time, programmable dead-time, and programmable over-current protection. Comprehensive protections cover lamp strike failure, filament failures, end-of-life conditions, and DC bus undervoltage reset.

Lighting, Ballast Controllers Feature Summary

• Integrates PFC, ballast control, and half-bridge driver functions for a one-chip solution
• Operates in critical conduction mode boost type PFC for high efficiency
• Features programmable parameters for preheat, run frequency, and dead-time
• Includes comprehensive protection against lamp faults and end-of-life conditions

Lighting, Ballast Controllers Applications

• Fluorescent lamp ballasts

Lighting, Ballast Controllers Procurement Notes

Verify the specific package variant (PDIP or SOIC) required for the design. Confirm that the component meets the necessary safety standards for the target application region. Check for availability of lead-free versions if RoHS compliance is mandatory. Ensure the supply voltage range matches the system requirements before ordering.

Lighting, Ballast Controllers Selection Notes

Select this IC for applications requiring integrated PFC and ballast control in a compact form factor. It is suitable for designs needing programmable timing and protection features without external complex circuitry. Consider the 600V rating for compatibility with standard line voltages. Evaluate the thermal performance based on the chosen package type.
