IR1150ISTRPBF

Overview

The IR1150ISTRPBF is a Power Factor Correction (PFC) integrated circuit manufactured by Infineon Technologies, formerly International Rectifier. It implements Universal PFC (UPFC) One Cycle Control technology to manage AC-DC power conversion. The device operates in a surface-mount SOIC-8 package and is designed for high-efficiency power factor correction applications.

Feature Summary

• Implements Universal PFC (UPFC) One Cycle Control architecture for comprehensive power management
• Supports both Continuous Conduction Mode (CCM) and Discontinuous Conduction Mode (DCM) operation
• Integrates a MOSFET gate driver stage for direct control of external switching components

Applications

• Universal input AC-DC power supplies
• Desktop computer Switching Mode Power Supplies (SMPS)
• Server power supply units
• Telecommunications power systems

Procurement Notes

Verify the specific suffix 'STRPBF' against the manufacturer's current datasheet to confirm tape-and-reel packaging and lead-free status. Confirm component availability as legacy products may have limited distribution channels or require alternative sourcing strategies.

Selection Notes

Select this component for designs requiring fixed-frequency CCM PFC with DCM transition capabilities. Ensure the application voltage range aligns with the IC's operational limits and that the thermal design accommodates the SOIC-8 package constraints.

Part Context

This part belongs to the IR1150 family of UPFC controllers. It shares functional similarities with the IR1152S and IR1155S but differs in frequency configuration and feature sets. It serves as a core controller for single-stage PFC solutions in general-purpose power electronics.

Replacement Considerations

The IR1150S is a pin-compatible variant. Verify if the specific reel packaging of the STRPBF suffix is critical for the assembly process before substituting with tube-packaged equivalents.
