ISL6730DFUZ-T

Overview

The ISL6730DFUZ-T is a Power Factor Correction (PFC) controller IC manufactured by Renesas Electronics Corporation. It utilizes a boost topology and operates in Continuous Conduction Mode (CCM). The device features a switching frequency of 124kHz and includes an internally clamped 12.5V gate driver capable of delivering 1.5A peak current. It supports universal line input AC/DC power systems up to 2kW. The component is housed in a 10-lead MSOP package with dimensions of 3.0 x 3.0 x 0.85 mm and operates within a temperature range of -40°C to +125°C.

Feature Summary

• Utilizes patent-pending negative capacitance technology to minimize zero-crossing distortion and reduce magnetic component size.
• Provides comprehensive system protection including cycle-by-cycle overcurrent, over-power limit, over-temperature, input brownout, output overvoltage, and undervoltage protection.
• Features an accurate input current error amplifier for precise input current shaping.

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 'F' indicates the MSOP package and 'T' denotes tape-and-reel packaging. Confirm the 'D' variant corresponds to the 124kHz switching frequency option. Ensure compatibility with existing PCB footprints for the 10-lead MSOP form factor. Check for RoHS compliance status as indicated in official documentation.

Selection Notes

Select this component for designs requiring CCM PFC control with integrated gate driving capabilities. The absence of skip mode distinguishes it from the ISL6730A/B variants, making it suitable for applications where consistent switching behavior is preferred over light-load efficiency optimization. Consider the 124kHz frequency for trade-offs between component size and switching losses.

Part Context

This part belongs to the ISL6730 family of active PFC controllers. The family includes variants A, B, C, and D, differentiated primarily by switching frequency and operational modes. The ISL6730D specifically offers the higher 124kHz frequency option without the power-saving skip mode found in the A and B versions.

Replacement Considerations

The ISL6730CFUZ-T is a compatible alternative within the same family, sharing the 124kHz frequency but lacking skip mode functionality similar to the DFUZ-T variant.

FAQ

Does the ISL6730DFUZ-T support skip mode?

No, the ISL6730D variant does not provide skip mode functionality; this feature is exclusive to the ISL6730A and ISL6730B models.

What is the switching frequency of the ISL6730DFUZ-T?

The ISL6730DFUZ-T operates at a fixed switching frequency of 124kHz.
