IR21593PBF

Lighting, Ballast Controllers Overview

The IR21593PBF is a dimmable ballast controller manufactured by Infineon Technologies, designed for high-frequency fluorescent lighting applications. It operates within a frequency range of 30 kHz to 230 kHz and supports supply voltages from 12 V to 16.5 V with a typical operating current of 10 mA. The device integrates control logic for dimming functionality and is housed in a 16-pin DIP package. Classified as obsolete, it serves as a dedicated solution for electronic ballast systems requiring precise frequency modulation and light output adjustment.

Lighting, Ballast Controllers Feature Summary

• Integrated dimming capability for adjustable light output control
• High-frequency operation suitable for electronic ballast applications
• CMOS logic design for low power consumption

Lighting, Ballast Controllers Applications

• Electronic fluorescent lamp ballasts
• Dimmable lighting control systems
• High-frequency AC power supplies for lamps

Lighting, Ballast Controllers Procurement Notes

Verify component obsolescence status before integration into new designs. Confirm availability through authorized distributors or surplus channels. Ensure compliance with RoHS directives as indicated in official documentation. Validate pin compatibility and thermal requirements for existing PCB layouts. Review end-of-life notices for long-term supply chain risks.

Lighting, Ballast Controllers Selection Notes

Select this component only for legacy system maintenance or specific retrofit projects where the original design architecture requires exact functional equivalence. Evaluate alternative modern controllers if new product development is underway. Consider package constraints and frequency stability requirements when comparing against contemporary ballast ICs.

Lighting, Ballast Controllers Part Context

This part belongs to the IR2159x series of ballast controllers from Infineon Technologies (formerly International Rectifier). It is specifically engineered for single-lamp electronic ballasts. The PBF suffix indicates a lead-free, halogen-free package compliant with environmental standards. The device replaces earlier generations of discrete control solutions in lighting electronics.

Lighting, Ballast Controllers Replacement Considerations

The IR21593PBF is marked as obsolete. Potential substitutes include newer Infineon ballast controllers such as the IR21592STRPBF, though pinout and feature sets must be verified against datasheets. Cross-referencing with other manufacturers' dimmable ballast ICs may require significant circuit redesign.
