IR21592

Lighting, Ballast Controllers Overview

The IR21592 is a dimmable ballast controller manufactured by Infineon Technologies, designed for electronic ballast applications. It operates within a frequency range of 18 kHz to 95 kHz and supports dimming functionality. The device is available in a 16-DIP package with through-hole mounting. It requires a supply voltage between 12 V and 16.5 V and draws a supply current of 10 mA. The component functions as a half-bridge driver integrated into the control logic.

Lighting, Ballast Controllers Feature Summary

• Integrated dimmable ballast controller supporting 1-10V input control
• Half-bridge topology for driving power stages
• Supports flicker-free hot start capabilities

Lighting, Ballast Controllers Applications

• Dimmable fluorescent lamp ballasts
• Automatic lighting control systems
• Emergency backup lighting facilities

Lighting, Ballast Controllers Procurement Notes

Verify component status carefully as the IR21592 is listed as obsolete or end-of-life in multiple distributor records. Confirm availability of alternative packages such as SOIC-16 if DIP inventory is unavailable. Check RoHS compliance status as some listings indicate non-compliance while others reference PbF variants. Ensure design-in timing accounts for potential supply constraints due to discontinuation notices.

Lighting, Ballast Controllers Selection Notes

Select this component for legacy designs requiring specific 18kHz to 95kHz operation ranges. Consider the 16-DIP package constraint for PCB layout. Evaluate thermal performance within the -40°C to 125°C operating temperature range. Verify compatibility with existing control circuitry for 1-10V dimming signals before integration.

Lighting, Ballast Controllers Part Context

The IR21592 belongs to Infineon's family of power management ICs specifically categorized under lighting and ballast controllers. It is often referenced alongside the IR21593 variant. The component serves as a core control chip for integrating full-dimming drive capabilities in electronic ballast designs, bridging control logic and power stage driving.

Lighting, Ballast Controllers Replacement Considerations

Public confirmed substitute part numbers are not explicitly documented in the provided source material. Designers should consult official Infineon documentation for direct replacements or evaluate the IR21593 variant for similar functional requirements.
