UCC2819DTR

Overview

The UCC2819DTR is a BiCMOS power factor preregulator controller designed for continuous conduction mode (CCM) operation. Manufactured by Texas Instruments, this component operates within a switching frequency range of 6 kHz to 220 kHz. It features undervoltage lockout thresholds at 10.2 V and 9.7 V. The device supports an operating temperature range from -40°C to +85°C and is housed in a 16-pin SOIC package.

Feature Summary

• Supports continuous conduction mode (CCM) power factor correction applications
• Features programmable output power control capabilities
• Includes built-in undervoltage lockout with defined threshold levels

Applications

• Power factor correction preregulators
• AC-DC power supplies
• Industrial power conversion systems

Procurement Notes

Verify the specific suffix 'DTR' indicates tape-and-reel packaging when ordering. Confirm the manufacturer is Texas Instruments to ensure authenticity. Check for moisture sensitivity labeling as indicated in related product attributes. Ensure compatibility with standard surface-mount assembly processes for SOIC packages.

Selection Notes

Select this component for designs requiring CCM PFC with adjustable frequency ranges up to 220 kHz. Consider the 16-pin SOIC footprint for layout constraints. Evaluate thermal performance within the specified -40°C to +85°C operational window. Compare against legacy UC series variants for pin compatibility and feature parity.

Part Context

This part belongs to the UCC2819 family of power factor correction controllers. It serves as a preregulator solution for AC-DC conversion. The device integrates essential control loops for high-efficiency power management. It complements other Texas Instruments PMIC offerings for complete power system design.

Replacement Considerations

The UCC2819D is the tube-packaged equivalent of the DTR variant. Verify package type requirements before substitution. Functional parameters remain consistent across packaging options.
