UC2854ADW

Overview

The UC2854ADWTR is an advanced high-power factor preregulator integrated circuit manufactured by Texas Instruments. It operates in a surface-mount 16-SOIC package and supports a switching frequency of 200 kHz. The device functions within a supply voltage range of 10V to 20V and maintains operation across a temperature range of -40°C to +85°C. It draws a working supply current of 250 µA. This component is designed for average current mode control applications.

Feature Summary

Implements average current mode control for power factor correction
Integrates zero-power detection capabilities
Supports high-power factor preregulator topologies

Applications

Power factor correction circuits
High-power factor preregulators
Switching power supply designs

Procurement Notes

Verify the specific suffix against official documentation, as variations such as TR indicate reel packaging while other suffixes may denote tape-and-reel or tube formats. Confirm RoHS compliance status and moisture sensitivity level requirements prior to integration into manufacturing processes to ensure compatibility with assembly standards.

Selection Notes

Select this component when designing systems requiring average current mode PFC control with a 200 kHz switching frequency. Ensure the application environment stays within the specified -40°C to +85°C operating temperature range. Verify that the 16-SOIC package dimensions fit the PCB layout constraints and that the 10V to 20V supply voltage aligns with the system architecture.

Part Context

This part belongs to the UC2854 family of power factor controllers from Texas Instruments. It serves as a specialized solution for improving efficiency in AC-DC conversion stages. The device is distinct from general PWM controllers by its dedicated PFC functionality and internal compensation networks tailored for power factor correction applications.

Replacement Considerations

Public confirmed substitute part numbers include UC2854DWTRG4 and UC2854BMDWREPG4. Verify pinout compatibility and electrical specifications before substitution.
