IR2159

Lighting, Ballast Controllers Overview

The IR2159 is a complete dimming ballast controller and 600V half-bridge driver integrated into a single IC. It features phase control for transformer-less lamp power sensing and regulation, enabling adaptation of non-dimming ballasts for dimming applications. The device includes closed-loop lamp power control, programmable preheat time and current, and ignition-to-dim timing. It supports a 0.5 to 5VDC dimming control input with adjustable min/max lamp power. Protection features include full lamp fault protection, brown-out protection, automatic restart, micro-power startup, zener clamped Vcc, and over-temperature protection.

Lighting, Ballast Controllers Procurement Notes

Verify component authenticity through authorized Infineon distributors or certified partners. Confirm package type availability, as the IR2159 is offered in 16-pin DIP and SOIC configurations. Check for end-of-life status or obsolescence notices, as older components may have limited supply chains. Ensure storage conditions comply with moisture sensitivity levels if applicable. Validate pinout compatibility with existing PCB layouts before procurement.

Lighting, Ballast Controllers Selection Notes

Select the IR2159 when designing dimming ballasts requiring integrated control and high-voltage driving capabilities. Consider its transformer-less sensing feature for simplified designs. Evaluate the programmable parameters such as preheat time and current to match lamp specifications. Assess the need for 0.5 to 5VDC dimming control interface compatibility. Review protection features like brown-out and over-temperature protection for system reliability requirements.

Lighting, Ballast Controllers Part Context

The IR2159 belongs to the family of dimming ballast controllers developed by International Rectifier, now part of Infineon Technologies. It combines power stage driving with intelligent control functions, targeting fluorescent lighting applications. The integration reduces component count and design complexity compared to discrete solutions. It represents a specialized solution for lighting control rather than general-purpose gate drivers.

Lighting, Ballast Controllers Replacement Considerations

Direct replacements are not explicitly listed in public documentation. Verify pinout and functional compatibility with alternative dimming ballast controllers from Infineon or other manufacturers. Ensure voltage ratings and package types match the original design constraints.
