IRS21541CD

Overview

The IRS21541CD is a high-voltage, self-oscillating ballast controller IC designed for fluorescent lamp electronic ballasts. It integrates a 600 V high-voltage MOSFET driver and operates without an external oscillator, simplifying circuit design. The device supports both single-ended and push-pull configurations, enabling efficient power conversion for lighting applications.

Feature Summary

Integrates a high-voltage gate driver with a built-in 600 V MOSFET
Self-oscillating operation eliminates the need for external timing components
Supports flexible single-ended and push-pull drive topologies

Applications

Electronic ballasts for fluorescent lamps
High-voltage lamp starting circuits
Resonant converter topologies in lighting systems

Procurement Notes

Verify component status as the IRS21541CD is listed as obsolete by multiple distributors. Confirm availability of alternative sources or last-time buy options if sourcing for new production. Ensure compatibility with existing PCB layouts when considering replacement strategies due to end-of-life status.

Selection Notes

Select this component for designs requiring integrated high-voltage driving capabilities without external oscillators. Evaluate thermal performance and voltage ratings against specific lamp requirements. Consider obsolescence risks and plan for potential redesigns using newer Infineon ballast controllers if long-term supply stability is required.

Part Context

This part belongs to the IRS2154x series of ballast controllers from Infineon Technologies (formerly International Rectifier). These devices are specialized for lighting control, offering integrated solutions that reduce component count and board space compared to discrete driver implementations.

Replacement Considerations

Check for direct pin-compatible successors within the IRS215xx family. Verify electrical parameters such as breakdown voltage and drive current against original specifications before substitution.
