IR21591

Lighting, Ballast Controllers Overview

The IR21591 is a ballast controller from Infineon Technologies designed for lighting applications. It operates within a frequency range of 30kHz to 230kHz and supports dimming functionality. The device is housed in a 16-DIP package with through-hole mounting. It requires a supply voltage between 12V and 16.5V and draws a supply current of 10 mA. The component functions as an integrated circuit for power management, specifically tailored for electronic ballast control.

Lighting, Ballast Controllers Feature Summary

• Integrated ballast controller with built-in dimming capability
• Wide operating frequency range suitable for various lamp types
• Designed for high-efficiency electronic ballast drivers

Lighting, Ballast Controllers Applications

• High efficiency electronic ballast drivers
• High power factor lighting systems
• Rapid start fluorescent lamp drivers

Lighting, Ballast Controllers Procurement Notes

Verify the specific frequency variant required, as datasheets may list ranges like 30kHz-230kHz. Confirm package type is 16-DIP. Check RoHS status as older revisions may not comply. Ensure compatibility with existing rapid start fluorescent lamp designs. Validate supply voltage requirements against system design.

Lighting, Ballast Controllers Selection Notes

Select this component for applications requiring integrated dimming and wide frequency operation. Consider the 16-DIP package for through-hole assembly needs. Evaluate the 10 mA supply current against power budget constraints. Ensure the 12V to 16.5V supply range matches available power rails. Verify suitability for rapid start fluorescent lamp types.

Lighting, Ballast Controllers Part Context

The IR21591 belongs to the IR2159 series of ballast controllers by Infineon Technologies. This series includes variants like the IR21592, which shares similar packaging but differs in frequency specifications. These components are part of Infineon's power management portfolio for lighting applications.

Lighting, Ballast Controllers Replacement Considerations

The IR21592 is a related part in the same series. Verify if the different frequency range (18kHz-95kHz for IR21592) meets application requirements. Both share the 16-DIP package.
