UC2853D

Overview

The UC2853D is a high power factor preregulator controller manufactured by Texas Instruments. It operates in continuous conduction mode (CCM) and utilizes average current mode control to achieve high power factor correction. The device supports an operating supply voltage up to 40 V and features undervoltage lockout thresholds at 11.5 V for turn-on and 9.5 V for turn-off. It includes overvoltage protection (OVP) and is rated for practical operating frequencies up to 0.115 MHz. The component is housed in an 8-pin SOIC package and functions as a single-phase PFC controller.

Feature Summary

Implements average current mode control for precise power factor correction
Integrates overvoltage protection circuitry
Features defined undervoltage lockout thresholds for stable startup

Applications

High power factor preregulators
Single-phase power factor correction systems
AC-DC power supply front ends

Procurement Notes

Verify the specific suffix 'D' indicates the SOIC-8 package variant when ordering. Confirm RoHS compliance status through official manufacturer documentation or authorized distributors, as environmental declarations may vary by production batch. Ensure the procurement channel provides valid traceability for quality assurance purposes.

Selection Notes

Select this component for applications requiring CCM operation with average current mode control. It is suitable for designs needing integrated OVP and specific UVLO thresholds. Consider the 8-pin SOIC package constraints for PCB layout. Evaluate thermal management requirements based on the specified operating temperature range of 0 to 70 degrees Celsius.

Part Context

This part belongs to the UCx853 series of high power factor preregulators from Texas Instruments. It is functionally related to the UC2853 and UC3853 variants, which share similar core control architectures but may differ in temperature ratings or packaging options. The UC2853D specifically denotes the commercial grade version in surface-mount packaging.

Replacement Considerations

Publicly confirmed substitute part numbers include UC2853DTRG4 and UC3853DTRG4. Verify pin compatibility and electrical specifications before substitution.
