UCC28019AP

Overview

The UCC28019AP is a Texas Instruments power factor correction controller designed for continuous conduction mode (CCM) applications. It operates within an extended temperature range from -40°C to +125°C and utilizes a PDIP-8 through-hole package. The device features a fixed switching frequency of 68.3 kHz and supports input voltages between 10 V and 21 V, with a nominal supply of 15 V. This component belongs to the UCC28019A series and is classified under PMIC power management ICs.

Feature Summary

• Implements average current mode control architecture for high-performance power factor correction
• Integrates soft overcurrent protection with programmable thresholds via external sensing components
• Includes input undervoltage detection with rapid response capabilities for system protection

Applications

• High-efficiency AC-DC power factor correction modules
• Industrial power supply front-end stages
• Telecommunications equipment power systems
• Data communication power adapters

Procurement Notes

Verify component authenticity due to end-of-life status. Confirm package integrity upon receipt as the PDIP-8 variant may have specific handling requirements. Cross-reference datasheet revisions to ensure compatibility with existing design parameters. Validate supplier authorization to mitigate counterfeit risks associated with discontinued semiconductor inventory.

Selection Notes

Select this through-hole variant when PCB assembly processes require DIP packaging rather than surface-mount options. Ensure the fixed 68.3 kHz switching frequency aligns with electromagnetic interference filtering requirements. Verify that the application power range falls within the optimal operational limits for CCM controllers before finalizing the bill of materials.

Part Context

This component is part of the UCC28019A family of PFC controllers. While the UCC28019AD and UCC28019ADR variants offer surface-mount SOIC-8 packages, the AP suffix specifically denotes the PDIP-8 through-hole configuration. All variants share identical core electrical characteristics and control algorithms despite physical packaging differences.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Designers should consult official discontinuation notices or contact Texas Instruments directly for recommended alternative components suitable for legacy system maintenance.
