UCC3817DW

Overview

The UCC3817DW is a BiCMOS Power Factor Preregulator manufactured by Texas Instruments. It is designed for high-performance power factor correction applications, operating within a commercial temperature range of 0°C to 70°C. The device utilizes a 16-pin Small Outline Integrated Circuit (SOIC) package suitable for surface-mount assembly. This component integrates essential control functions required for efficient AC-DC conversion systems.

Feature Summary

• Implements BiCMOS technology for enhanced power factor preregulation performance
• Provides integrated control logic for power factor correction circuits
• Supports surface-mount installation via a standard 16-pin SOIC footprint

Applications

• Power factor correction in AC-DC power supplies
• BiCMOS power factor preregulator designs
• Commercial electronic equipment requiring PFC compliance

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to ensure correct package type and temperature rating. Confirm RoHS compliance status and lead times directly with authorized distributors or Texas Instruments prior to procurement. Ensure the selected variant matches the required industrial specifications.

Selection Notes

Select this component when designing power factor correction stages requiring BiCMOS integration. Consider the 16-pin SOIC package constraints and the 0°C to 70°C commercial operating range. Evaluate thermal management requirements for surface-mount applications and verify compatibility with existing PCB footprints.

Part Context

This part belongs to the UCC3817 family of power factor controllers from Texas Instruments. It shares functional similarities with other variants like the UCC3817AD but differs in packaging and temperature specifications. The DW suffix typically denotes a tape-and-reel or tube packaged SOIC version intended for automated assembly processes.

Replacement Considerations

The UCC3817ADG4 is a documented equivalent within the same product family. Verify pinout compatibility and electrical characteristics before substitution. Other variants such as UCC3817AD may require package adaptation due to differences in mounting style.
