IRS2500STRPBF

Overview

The IRS2500STRPBF is a Power Factor Correction (PFC) controller from Infineon Technologies, designed for Critical Conduction Mode (CRM) operation. It utilizes an 8-SOIC surface-mount package and operates within a supply voltage range of 11.5V to 20V. The device features a low startup current of 50 µA and supports operating temperatures from -25°C to 125°C. As a CRM controller, it optimizes efficiency across varying load conditions by adjusting switching frequency dynamically.

Feature Summary

• Supports Critical Conduction Mode (CRM) for optimized power factor correction
• Integrated high-voltage startup circuitry with low quiescent current
• Designed for robust performance in variable load applications

Applications

• Power factor correction stages in AC-DC converters
• Universal input power supplies
• Consumer electronics power adapters

Procurement Notes

Verify the exact suffix 'STRPBF' against official Infineon documentation to confirm reel packaging and tape specifications. Confirm that the component status is active or identify valid obsolescence notices. Ensure the ordering part number matches the specific temperature grade and package variant required for your design.

Selection Notes

Select this component when designing for critical conduction mode PFC applications requiring simplified control loops. Consider the 8-SOIC package constraints for thermal management and PCB layout. Evaluate the 11.5V to 20V supply range compatibility with your auxiliary power stage.

Part Context

This part belongs to the IRS2500 family of PFC controllers. It shares functional similarities with other CRM controllers but is distinguished by its specific pinout, startup characteristics, and Infineon's proprietary control architecture. It serves as a dedicated solution for single-stage PFC implementations.

Replacement Considerations

Publicly documented substitutes include onsemi NCP1608BDR2G. Verify electrical parameter compatibility and pin-to-pin equivalence before substitution.
