UCC2819PW

Overview

The UCC2819PW is a BiCMOS power factor preregulator manufactured by Texas Instruments, housed in a 16-pin SOIC-Narrow package. It operates within an industrial temperature range of -40°C to +85°C and features a fixed switching frequency of 250 kHz. The device draws a typical operating supply current of 150 µA. This component is classified under Power Factor Correction (PFC) controllers within the PMIC category.

Feature Summary

BiCMOS technology implementation for high-performance power factor correction
Fixed internal switching frequency operation
Low quiescent supply current consumption

Applications

Power factor correction pre-regulators
AC-DC power conversion systems

Procurement Notes

Verify the specific suffix 'PW' against the manufacturer's official documentation to confirm the exact package variant and tape-and-reel or tube configuration. Confirm RoHS compliance status through the latest datasheet revision notes before procurement.

Selection Notes

Select this component for applications requiring a dedicated PFC controller with a fixed 250 kHz switching frequency. Ensure the design accommodates the SOIC-Narrow-16 footprint and operates within the specified -40°C to +85°C temperature envelope.

Part Context

This part belongs to the UCC2819A series of power factor correction controllers. It utilizes BiCMOS technology to achieve efficient power factor preregulation. The device is designed for standalone PFC stages in AC-DC power supplies.

Replacement Considerations

Consult the manufacturer's obsolescence notices and cross-reference tools for verified substitute part numbers. Verify pinout compatibility and electrical specifications before substituting.
