UC2854AN

Overview

The UC2854AN is an enhanced high power factor preregulator controller manufactured by Texas Instruments. It operates within a supply voltage range of 10V to 20V and features a fixed switching frequency of 200 kHz. The device supports through-hole installation in a 16-pin PDIP package. It functions across a temperature range from -40°C to +85°C, with a typical operating supply current of 250 µA.

Feature Summary

Integrated zero-power detection capability for efficient operation at low loads
Sinusoidal input current shaping for improved power factor correction
Built-in power limiting functionality to protect against overload conditions

Applications

High power factor pre-regulators
Power factor correction circuits
AC-DC power supplies

Procurement Notes

Verify the specific suffix 'AN' confirms the PDIP-16 through-hole package variant. Confirm the manufacturer is Texas Instruments. Check RoHS compliance status via official documentation. Ensure the component matches the UC2854A series specifications before integration into designs requiring 200 kHz switching frequencies.

Selection Notes

Select this component when a through-hole PFC controller with 200 kHz switching is required. Compare against UC3854AN for industrial temperature ranges if extended limits are needed. Consider UC2854ADWTR for surface-mount applications. Verify pin compatibility with existing PCB layouts designed for 16-pin DIP packages.

Part Context

Part of the UC2854A family of power factor correction controllers. Designed for universal AC input applications. Complements other UC385x series devices offering similar functionality with varying thermal or packaging options.

Replacement Considerations

UC3854AN offers identical electrical performance but is rated for commercial temperature range (0°C to +70°C). UC2854ADWTR provides the same function in SOIC-16 surface-mount package.
