IRS2500SPBF

Overview

The IRS2500SPBF is a Power Factor Correction (PFC) controller IC manufactured by Infineon Technologies, designed for Critical Conduction Mode (CRM) operation. It operates within a supply voltage range of 11.5V to 20V and features a low startup current of 50 µA. The component is housed in an 8-SOIC surface-mount package with a width of 3.90mm. It supports an operating temperature range from -25°C to +125°C and carries a Moisture Sensitivity Level (MSL) rating of 2, allowing for one year of shelf life under standard conditions.

Feature Summary

• Supports Critical Conduction Mode (CRM) PFC control strategies
• Integrated high-voltage startup circuitry for reduced external component count
• Compatible with CMOS and TTL logic input levels

Applications

• Power factor correction stages in AC-DC power supplies
• Adaptive lighting drivers requiring CRM topology
• General-purpose offline power conversion systems

Procurement Notes

Verify the obsolete status of this component before procurement planning. Confirm availability through authorized distributors or qualified second-source suppliers. Ensure that any substitute parts meet all electrical and mechanical specifications required for your specific design implementation. Check for RoHS compliance and environmental declarations if applicable to your region.

Selection Notes

Select this component for designs specifically requiring CRM PFC control in an 8-pin SOIC package. Consider the limited supply chain due to end-of-life status when designing new products. Evaluate alternative modern controllers with active manufacturing support for long-term production viability. Ensure the 11.5V to 20V VCC range aligns with your system's auxiliary power capabilities.

Part Context

This part belongs to the IRS2500 family of PFC controllers from Infineon Technologies. It is distinct from gate driver-only ICs in the same naming convention. The SPBF suffix indicates a lead-free, halogen-free variant compliant with specific environmental standards. It serves as a dedicated controller rather than a combined driver-controller solution.

Replacement Considerations

The NCP1608BDR2G from onsemi is documented as a similar replacement option.
