UC3853D

Overview

The UC3853D is a high power factor preregulator controller from Texas Instruments, designed for single-phase power factor correction applications. It operates within an operating supply voltage range of 12V to 40V and supports a practical maximum frequency of 0.115 MHz. The device utilizes average current mode control and features undervoltage lockout thresholds at 9.5V (off) and 11.5V (on). It is housed in an 8-SOIC package with a wide operating temperature range of 0°C to 70°C.

Feature Summary

Implements average current mode control for precise power factor correction
Includes integrated overvoltage protection mechanisms
Features built-in undervoltage lockout for reliable startup and shutdown

Applications

Single-phase power factor correction preregulators
High power factor AC-DC power supplies
Universal input power conversion systems

Procurement Notes

Verify the specific suffix 'D' confirms the SOIC-8 surface-mount package variant rather than the PDIP through-hole version. Confirm the commercial grade temperature rating aligns with system requirements. Ensure the component matches the original datasheet specifications for pinout and electrical characteristics before integration into production designs.

Selection Notes

Select this component for applications requiring a dedicated single-phase PFC controller with average current mode control. It is suitable for designs needing integrated overvoltage protection and robust startup logic via UVLO. Consider the 8-SOIC package for surface-mount assembly constraints and verify compatibility with the target switching frequency limits.

Part Context

The UC3853D belongs to the UC385x family of high power factor preregulators manufactured by Texas Instruments. This series focuses on improving efficiency and reducing harmonic distortion in AC-DC power conversion stages. The D suffix specifically denotes the plastic small-outline package variant within this product line.

Replacement Considerations

UC3853N serves as the PDIP equivalent. UC3853DTRG4 offers the same SOIC package with tape-and-reel packaging. UC2853 variants provide industrial temperature ratings.
