ISL6731BFBZ-T

Overview

The ISL6731BFBZ-T is a Power Factor Correction (PFC) controller from Renesas Electronics Corporation, designed for continuous conduction mode (CCM) applications. It operates within a switching frequency range of 56.5kHz to 70.7kHz and features a startup current of 106 µA. The device supports a supply voltage range of 15V to 20V and functions reliably across an operating temperature range of -40°C to 125°C. It is housed in a 14-SOIC package with a width of 3.90mm.

Feature Summary

• Supports continuous conduction mode (CCM) power factor correction
• Integrated control logic for fixed-frequency operation
• Designed for high-efficiency AC-DC power conversion

Applications

• AC-DC power supplies
• Power factor correction circuits
• Industrial power systems

Procurement Notes

Verify the specific suffix BFBZ-T against official Renesas documentation to confirm the tape-and-reel packaging format and exact electrical characteristics. Confirm component status as discontinued or obsolete through authorized distributors before procurement planning. Ensure compatibility with existing board layouts and thermal management requirements.

Selection Notes

Select this component for CCM PFC designs requiring a switching frequency up to 70.7kHz. Consider the 14-SOIC package constraints and the specified supply voltage range of 15V to 20V. Evaluate thermal performance within the -40°C to 125°C operating range for the target application environment.

Part Context

The ISL6731 series includes variants like the ISL6731AFBZ-T, which offers a higher switching frequency range of 111kHz to 138kHz. Both share similar packaging and operational parameters but differ in frequency specifications. This distinction allows designers to choose based on magnetic component size and efficiency targets.
