IR2159S

Lighting, Ballast Controllers Overview

The IR2159S is a ballast controller IC designed for electronic lighting applications. It operates within a frequency range of 25 kHz to 95 kHz and supports dimming functionality. The device is housed in a 16-SOIC surface-mount package. It requires a supply voltage between 12 V and 16.5 V and draws a typical supply current of 10 mA. The component is rated for an operating temperature range from -40°C to 125°C.

Lighting, Ballast Controllers Feature Summary

• Integrated dimming control capability for adjustable light output
• High-voltage half-bridge gate driver topology for lamp ignition
• Built-in protection mechanisms against open-circuit and short-circuit conditions

Lighting, Ballast Controllers Applications

• Electronic ballasts for rapid start fluorescent lamps
• Dimmable lighting systems requiring high power factor
• Compact electronic ballast designs for commercial fixtures

Lighting, Ballast Controllers Procurement Notes

Verify the specific suffix (e.g., STRPBF) to confirm lead-free compliance and RoHS status, as standard versions may differ. Confirm package type accuracy, as SOIC variants exist alongside DIP equivalents. Check manufacturer discontinuation notices for long-term availability constraints before finalizing design specifications.

Lighting, Ballast Controllers Selection Notes

Select this component for applications requiring integrated control and driving functions in a single package. Ensure the design accommodates the specified 12 V to 16.5 V supply range. Verify that the 16-SOIC footprint matches the PCB layout requirements. Consider thermal management capabilities given the 125°C maximum junction temperature rating.

Lighting, Ballast Controllers Part Context

The IR2159S belongs to Infineon's family of dedicated ballast controllers, often paired with similar models like the IR21592. It serves as a core component in electronic lighting circuits, replacing discrete solutions by integrating oscillator, dimming, and gate drive stages into one semiconductor unit.

Lighting, Ballast Controllers Replacement Considerations

The IR21592 is a pin-compatible alternative available in a 16-DIP package. Verify package compatibility and electrical parameter alignment when substituting. No other direct public substitutes are confirmed in the provided documentation.
