UC2854BQ-TI

Overview

The UC2854BQ-TI is an advanced high-power factor preregulator from Texas Instruments, designed for average current mode control. It operates within a switching frequency range of 80 kHz to 120 kHz and features a startup current of 250 µA. The component is housed in a 20-PLCC (9x9) package with J-leads. It supports industrial temperature ranges and functions as a power factor correction IC.

Feature Summary

Implements average current mode control for enhanced power factor correction
Features integrated soft-start and brown-in/brown-out protection circuits
Includes internal oscillator and error amplifier for stable regulation

Applications

High-power factor preregulators in AC-DC power supplies
Power factor correction stages in computer peripherals
Industrial power supply systems requiring high efficiency

Procurement Notes

Verify the specific suffix 'TI' indicates original manufacturer packaging when sourcing. Confirm the 20-PLCC package variant matches design requirements. Ensure compatibility with average current mode control topologies. Check datasheet revisions for any updates to electrical characteristics or pin configurations before finalizing procurement.

Selection Notes

Select this component for applications requiring precise average current mode control. Consider the 80 kHz to 120 kHz frequency range for EMI management. Evaluate the 20-PLCC package for thermal and mechanical fit. Compare against UC2854 variants if different operating temperatures or packages are needed.

Part Context

Part of the UC2854 family of high-power factor preregulators. Designed to replace older UC1854/UC2854 designs with improved performance. Supports compliance with international power quality standards. Integrates multiple functions into a single IC to reduce component count.

Replacement Considerations

UC2854BQ is the direct equivalent without tape-and-reel packaging. UC2854AN/BN offer PDIP-16 through-hole options. UC3854 provides military-grade temperature range variants.
