Overview
The IRS2980SPBF is a high-side LED driver IC manufactured by Infineon Technologies, designed for automotive and industrial applications. It integrates PFC and ballast control functions within an 8-SOIC package. The device supports wide input voltage ranges up to 75V and features analog and PWM dimming capabilities. It operates as a step-down (Buck) DC-DC controller, providing efficient power management for lighting systems.
Feature Summary
- Integrates Power Factor Correction (PFC) and ballast control functions
- Supports analog and PWM dimming methods
- Designed for high-side LED driving configurations
- Operates with wide input voltage range up to 75V
Applications
- Automotive lighting systems
- Industrial LED lighting
- Fluorescent lamp ballast replacement
- High-efficiency LED drivers
Procurement Notes
Verify the specific revision level and RoHS compliance status before procurement, as component specifications may vary across manufacturing batches. Confirm that the 8-SOIC package dimensions match your PCB footprint requirements. Ensure compatibility with your system's input voltage range, which extends up to 75V, and validate that the integrated PFC and ballast functions align with your design topology. Check for any end-of-life notices or recommended new design alternatives if applicable.
Selection Notes
Select this component when a combined PFC and ballast solution is required for high-side LED applications. It is suitable for designs needing both power factor correction and current regulation in a single IC. Consider its 75V input tolerance for higher voltage bus applications. Evaluate the analog and PWM dimming interfaces against your control system requirements. This IC simplifies design by integrating multiple functions, reducing component count compared to discrete solutions.
Part Context
The IRS2980SPBF belongs to Infineon's family of LED driver ICs, specifically targeting applications requiring integrated power management. It complements other LED controllers by offering a compact solution for high-side driving. The 8-SOIC package allows for space-constrained designs. It is distinct from general-purpose gate drivers like the IR2183SPBF, focusing instead on lighting-specific control loops and dimming features.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Verify functional equivalence with other high-side LED drivers if direct substitution is needed.
