UCC28064ADR

Overview

The UCC28064ADR is a Natural Interleaving Transition-Mode Power Factor Correction (PFC) controller manufactured by Texas Instruments. It operates within an extended temperature range of -40°C to +125°C and utilizes a 16-pin SOIC-Narrow package for surface-mount installation. This component is designed to enhance light-load efficiency in power supply applications.

Feature Summary

• Implements natural interleaving transition-mode control architecture
• Optimized for improved efficiency during light-load operating conditions

Applications

• Power factor correction stages in AC-DC converters
• High-efficiency power supply designs requiring low standby power consumption

Procurement Notes

Verify the specific suffix 'ADR' corresponds to the tape-and-reel packaging format when sourcing. Confirm that the SOIC-Narrow-16 footprint matches the target PCB layout requirements. Ensure the selected variant meets the required thermal operating range specifications for the intended application environment.

Selection Notes

Select this controller for designs prioritizing high power factor with reduced acoustic noise and improved efficiency at partial loads. The transition-mode operation offers a balance between performance and complexity compared to continuous conduction mode alternatives.

Part Context

This device belongs to the UCC28064A series of PFC controllers. It shares functional similarities with other transition-mode controllers but distinguishes itself through specific enhancements in light-load performance and natural interleaving capabilities for multi-phase implementations.

Replacement Considerations

The UCC28064ADT serves as a tray-packaged alternative within the same family. Cross-reference pinouts and electrical characteristics before substituting with other TI PFC controllers.
