ISL6731BFBZ

Overview

The ISL6731BFBZ is a Power Factor Correction (PFC) controller IC manufactured by Renesas Electronics Corporation. It operates in Continuous Conduction Mode (CCM) with a switching frequency range of 56.5kHz to 70.7kHz. The device supports a supply voltage of 15V to 20V and features an input current of 106 µA. It is designed for surface mount installation in a 14-SOIC package (0.154" width, 3.90mm). The component is rated for an operating temperature range of -40°C to 125°C.

Feature Summary

Supports continuous conduction mode (CCM) power factor correction applications
Integrated control logic for boost topology PFC systems
Designed for operation within specified industrial temperature ranges

Applications

AC/DC power conversion systems
Power factor correction circuits
Industrial power supplies

Procurement Notes

Verify the specific suffix BFBZ against official Renesas documentation to confirm the exact switching frequency variant and package configuration. Confirm end-of-life status as the component is listed as obsolete. Ensure compatibility with existing board layouts for the 14-SOIC footprint before procurement.

Selection Notes

Select this component for CCM PFC designs requiring a fixed lower frequency range around 70.7kHz. Compare against the AFBZ variant if higher frequency operation near 138kHz is required. Verify that the 14-SOIC package dimensions fit the target PCB constraints and thermal management requirements.

Part Context

The ISL6731 series includes variants such as the ISL6731AFBZ and ISL6731BFBZ, differentiated primarily by their switching frequency specifications. Both belong to the PFC controller family from Renesas, utilizing similar control architectures but optimized for different electromagnetic interference or transformer size trade-offs based on frequency selection.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source data. Consult Renesas technical support for direct replacements or cross-reference options.
