IRS25411STRPBF

Overview

The IRS25411STRPBF is a high-voltage, high-frequency buck control IC designed for constant current LED regulation. It operates with a supply voltage range of 8V to 16.6V and supports a switching frequency of 500kHz. The device features PWM dimming capability and includes short-circuit protection. Packaged in an 8-SOIC format, it functions as a DC-DC controller without internal switches, suitable for applications requiring efficient power conversion within a junction temperature range of -25°C to 125°C.

Feature Summary

Supports PWM dimming for precise light control
Integrates short-circuit protection mechanisms
Designed for high-frequency buck topology operation

Applications

Constant current LED lighting systems
High voltage LED driver circuits
General purpose DC-DC buck regulation

Procurement Notes

Verify the specific suffix STRPBF indicates tape-and-reel packaging when sourcing. Confirm RoHS3 compliance status through official Infineon documentation prior to integration. Ensure the 8-SOIC package dimensions match the target PCB footprint requirements. Cross-reference the manufacturer part number against authorized distributors to avoid counterfeit components.

Selection Notes

Select this component for designs requiring a dedicated buck controller rather than an integrated switch solution. Consider the 500kHz operating frequency for balancing efficiency and component size. Evaluate the 8V to 16.6V supply range against the system's available rail. Verify thermal management capabilities for the specified junction temperature limits.

Part Context

This part belongs to Infineon's family of AC-DC LED driver ICs and controllers. It serves as a successor or alternative to legacy parts like the IRS2541SPBF, which has been discontinued. The series focuses on delivering high efficiency and reduced external component counts for LED lighting applications.
