UC2854BMDWREPG4

Overview

The UC2854BMDWREPG4 is an enhanced product advanced high-power factor preregulator manufactured by Texas Instruments. It operates within a supply voltage range of 10 V to 20 V, with a nominal input voltage of 18 V. The device utilizes current-mode control and pulse width modulation techniques. It is housed in a 16-SOIC package (SOP, SOP16,.4) measuring 10.3 mm in length. The component supports an extended industrial temperature range from -55°C to +125°C.

Feature Summary

• Implements average current mode control for power factor correction applications
• Features zero power detection capability
• Supports operation across an extended industrial temperature range

Applications

• High-power factor preregulator circuits
• Power factor correction systems requiring extended temperature stability

Procurement Notes

Verify the specific suffix 'EP' indicates Enhanced Product status and confirm RoHS compliance details via the official datasheet. Ensure the SOIC-16 package dimensions match your PCB footprint requirements. Cross-reference the manufacturer part number against authorized distributors to confirm authenticity and availability status before finalizing procurement decisions.

Selection Notes

Select this component when designing power factor correction circuits that require operation at elevated temperatures up to 125°C. The 16-SOIC package is suitable for surface-mount assembly. Verify that the 10 V to 20 V supply voltage range aligns with your system's power delivery architecture and that the current-mode control strategy meets your specific regulation needs.
