UCC2818AD

Overview

The UCC2818AD is a BiCMOS power factor preregulator manufactured by Texas Instruments. It operates within a switching frequency range of 6 kHz to 220 kHz and supports an operating temperature range from -40°C to +85°C. The device is housed in a 16-SOIC package with a width of 3.90 mm. It functions as an average current mode controller for power factor correction applications.

Feature Summary

Implements average current mode control for high power factor preregulation
Utilizes BiCMOS technology for integrated circuit performance
Provides internal compensation and protection features for AC-DC front ends

Applications

Average current mode PFC controllers
AC-DC power supplies
Power factor correction preregulators

Procurement Notes

Verify the specific suffix 'AD' against the official datasheet to confirm the commercial grade temperature rating and tube packaging format. Ensure compatibility with the 16-SOIC footprint and validate that the 6 kHz to 220 kHz frequency range meets the design requirements. Cross-reference the manufacturer part number with authorized distributors to avoid obsolete or counterfeit components.

Selection Notes

Select this component for designs requiring average current mode PFC control without automotive qualification. The UCC2818AD is suitable for industrial and commercial applications operating up to 85°C. Consider the UCC2818ADR variant if reel packaging is preferred over tubes. Verify that the input voltage and current sensing requirements align with the device's internal reference and comparator specifications.

Part Context

The UCC2818AD belongs to the UCC2818A family of BiCMOS power factor preregulators. It serves as a non-automotive grade alternative to the UCC2818AQDRQ1, which holds AEC-Q100 certification. This series is designed to improve efficiency and reduce harmonic distortion in AC-DC conversion systems compared to traditional discontinuous conduction mode solutions.
