IRS2541SPBF

Overview

The IRS2541SPBF is a DC-DC controller IC designed for LED lighting applications, manufactured by Infineon Technologies. It utilizes a step-down (buck) topology and supports PWM dimming control. The device operates within a supply voltage range of 9V to 15.6V and features an internal switching frequency of 500kHz. It is housed in an 8-SOIC package with a width of 3.90mm. The component functions as a high-side/low-side driver without an integrated internal switch. It is rated for a junction temperature range of -25°C to 150°C and holds a Moisture Sensitivity Level (MSL) of 2 (1 year).

Feature Summary

Supports PWM dimming for precise LED brightness control.
Integrates high-side and low-side gate drivers for buck converter topologies.
Operates at a fixed switching frequency of 500kHz.

Applications

LED lighting driver circuits
Buck converter power supplies
General-purpose DC-DC control systems

Procurement Notes

Verify the obsolete status of this specific part number before procurement planning. Confirm availability of the recommended substitute, IRS25411STRPBF, which is currently active. Ensure that the replacement component meets all original electrical and mechanical specifications required for the design. Check for any changes in packaging or pinout compatibility during the transition from the discontinued model to the new version.

Selection Notes

Select this component for designs requiring a dedicated buck controller with integrated gate drivers. Consider the 500kHz switching frequency when designing external inductor and capacitor values. Verify that the operating voltage range of 9V to 15.6V aligns with the system power supply. Note that the internal switch is not included, requiring external MOSFETs. Evaluate thermal management requirements given the 150°C maximum junction temperature rating.

Part Context

The IRS2541SPBF belongs to the IRS2541 family of LED drivers from Infineon Technologies. It serves as a specialized controller for managing LED strings in lighting applications. The device is part of a broader portfolio of power management solutions designed for efficiency and reliability. Its integration of gate drivers simplifies the implementation of synchronous rectification in buck converters.

Replacement Considerations

The IRS2541SPBF is obsolete. The confirmed public substitute is IRS25411STRPBF. Verify functional equivalence regarding pinout and electrical parameters before substitution.
