Overview
The IRS2541CD is a high-voltage, high-frequency buck control IC designed for constant current LED driver applications. It operates with a supply voltage range of 8V to 16.6V and supports PWM dimming capabilities. The component utilizes a buck topology and functions as a DC-DC controller without an internal switch. It is available in a die configuration and is rated for a junction temperature range of -25°C to 125°C. The switching frequency is specified at 500kHz. This part is classified as obsolete and is no longer manufactured by Infineon Technologies.
Feature Summary
- High-voltage buck control architecture for LED lighting
- Supports PWM dimming functionality
- Designed for high-frequency operation
Applications
- Constant current LED drivers
- Buck converter topologies
- LED lighting systems
Procurement Notes
Verify the obsolete status of the IRS2541CD before procurement planning. As this component is no longer manufactured, availability is limited to existing stock or surplus channels. Confirm package integrity and authenticity through authorized distributors. Evaluate replacement options such as the IRS25411STRPBF for new designs to ensure long-term supply chain stability and compliance with current manufacturing standards.
Selection Notes
Select this component only for legacy system maintenance or repair where specific form-factor compatibility is required. For new designs, consider modern equivalents like the IRS25411STRPBF which offer similar buck control features in active production. Ensure that the design accommodates the die package type and verify that the operating voltage and frequency parameters align with the target LED load requirements and thermal management constraints.
Part Context
The IRS2541CD belongs to Infineon's portfolio of AC-DC LED driver ICs and controllers. It is part of the broader IRS2541 family, which includes variants like the IRS25411SPBF and IRS25411STRPBF. These components are engineered to deliver high efficiency and power quality for LED applications. The IRS2541CD specifically represents an earlier iteration in this series, characterized by its high-voltage buck control capabilities and die-level packaging.
Replacement Considerations
The IRS25411STRPBF is listed as a similar substitute for the obsolete IRS2541CD. Verify pinout compatibility and electrical parameter alignment before substitution.
