ISL6730AFUZ-T

Overview

The ISL6730AFUZ-T is a Power Factor Correction (PFC) controller IC utilizing boost topology, designed for AC/DC power systems up to 2kW with universal line input. It operates in Continuous Conduction Mode (CCM) and features internally clamped 12.5V gate driver delivering 1.5A peak current. The device supports switching frequencies of 124kHz and includes protection against overcurrent, overvoltage, and overtemperature.

Feature Summary

• Utilizes negative capacitance technology to minimize zero crossing distortion
• Provides cycle-by-cycle overcurrent and output overvoltage protection
• Transitions into power saving skip mode during light load conditions

Applications

• Desktop computer AC/DC adaptors
• Laptop computer AC/DC adaptors
• TV AC/DC power supplies
• AC/DC brick converters

Procurement Notes

Verify the specific suffix 'AFUZ-T' against official Renesas documentation to confirm the 124kHz frequency option and tape-and-reel packaging configuration. Ensure compatibility with existing board layouts regarding the MSOP package dimensions and pinout assignments before finalizing procurement decisions.

Selection Notes

Select this component for designs requiring CCM PFC control with low THD performance. The integrated gate driver simplifies external component count. Consider the 124kHz switching frequency for magnetic component size optimization compared to lower frequency variants within the same family.

Part Context

This part belongs to the ISL6730 series of active PFC controllers from Renesas Electronics. The series includes variants with different switching frequencies and skip mode capabilities. The ISL6730A variant specifically operates at 124kHz and includes skip mode functionality for improved light-load efficiency.

Replacement Considerations

ISL6730BFUZ-T offers similar functionality but switches at 62kHz. ISL6730CFUZ-T provides 124kHz operation without skip mode. Verify electrical parameters and pin compatibility when substituting.
