UCC28063DR

Overview

The UCC28063DR is a Natural Interleaving transition-mode power factor correction (PFC) controller manufactured by Texas Instruments. It operates within a supply voltage range of 14V to 21V and supports switching frequencies up to 500 kHz. The device is designed for surface-mount installation in a 16-SOIC package with a width of 3.90mm. It functions reliably across an extended temperature range from -40°C to +125°C. The component draws a startup current of 100 µA and is classified under PMIC PFC controllers.

Feature Summary

• Implements Natural Interleaving technology to enhance performance in transition-mode PFC applications
• Provides improved immunity against audible noise interference during operation
• Supports high-frequency switching capabilities up to 500 kHz for compact design

Applications

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

Procurement Notes

Verify the specific suffix 'DR' corresponds to the tape-and-reel packaging format when sourcing. Confirm that the 16-SOIC footprint matches the target PCB layout dimensions. Ensure compliance with RoHS3 standards if required by the end product specifications. Cross-reference the manufacturer part number UCC28063DR with authorized distributors to ensure authenticity.

Selection Notes

Select this component for applications requiring transition-mode PFC control with interleaved phase benefits. It is suitable for designs needing wide operating temperature ranges and high switching frequencies. Consider the 16-pin SOIC package constraints for thermal management and board space. Evaluate compatibility with existing reference designs such as the UCC28063EVM-723 for rapid prototyping.
