UCC28063ADR

Overview

The UCC28063ADR is a transition-mode power factor correction controller manufactured by Texas Instruments. It operates within a supply voltage range of 14V to 21V and features an internal startup current of 100 µA. The device supports surface-mount installation in a 16-SOIC package (0.154" width) and functions reliably across an extended temperature range from -40°C to +125°C. Designed for high efficiency, it utilizes the Natural Interleaving™ architecture to manage multiple phases.

Feature Summary

• Implements Natural Interleaving technology for enhanced multi-phase performance
• Operates in transition mode to optimize power factor correction efficiency
• Supports robust operation across wide industrial temperature ranges

Applications

• Power management solutions for digital televisions
• 300W PFC pre-regulator designs with 390V output
• Universal input AC-DC conversion systems (85V to 265V)

Procurement Notes

Verify component authenticity through authorized channels. Confirm RoHS compliance status and check for specific packaging variants such as cut tape or reel options. Ensure the ordering suffix matches the required package type and verify lead times against current production schedules.

Selection Notes

Select this controller for applications requiring high power density and low harmonic distortion. Consider the 16-SOIC footprint constraints and thermal dissipation requirements. Evaluate compatibility with existing transformer designs and ensure the control loop stability meets system specifications.
