UCC28065DR

Overview

The UCC28065DR is a Power Factor Correction (PFC) controller from Texas Instruments, designed for natural interleaving transition-mode applications. It operates within a switching frequency of 800 kHz and supports an operating temperature range from -40°C to +125°C. The component is housed in a 16-pin SOIC package suitable for surface mount technology.

Feature Summary

• Implements natural interleaving control for enhanced power factor correction performance
• Supports transition-mode operation for efficient power management
• Integrated thermal protection mechanisms for reliable operation

Applications

• High-efficiency power supplies
• Computer peripheral power units
• Telecommunications equipment

Procurement Notes

Verify the specific suffix 'DR' corresponds to the tape-and-reel packaging configuration required for your assembly line. Confirm that the SOIC-16 footprint matches your PCB design constraints. Ensure compatibility with the intended input voltage ranges and thermal management requirements before finalizing procurement orders.

Selection Notes

Select this component when designing systems requiring high-frequency interleaved PFC solutions. Consider the 800 kHz switching capability for reduced passive component size. Evaluate the wide operating temperature range for harsh environment suitability. Compare against standard CCM controllers if continuous conduction is not required.

Part Context

This device belongs to the UCC28065 series of PFC controllers. It shares functional similarities with other transition-mode controllers but offers specific interleaving benefits. The DR suffix indicates reel packaging, distinguishing it from tube-packaged variants like the UCC28065DT.

Replacement Considerations

The UCC28065DT serves as a pin-compatible alternative with identical electrical characteristics but differs in packaging format. Verify board space and handling requirements when substituting between reel and tube options.
