Overview
The UCC28063AD is a Natural Interleaving Transition-Mode Power Factor Correction (PFC) controller manufactured by Texas Instruments. It operates within a supply voltage range of 14V to 21V and supports switching frequencies up to 45 kHz. The device features a maximum duty cycle of 99% and functions reliably across an extended temperature range from -40°C to +125°C. It is housed in a 16-pin SOIC package with narrow body configuration, designed for surface-mount installation.
Feature Summary
- Implements natural interleaving transition-mode control to enhance power factor correction efficiency
- Provides improved immunity against audible noise and input surge disturbances
- Supports high duty cycle operation up to 99% for flexible converter design
Applications
- Power factor correction stages in AC-DC power supplies
- High-efficiency LED lighting drivers
- Consumer electronics power adapters
Procurement Notes
Verify the specific suffix 'AD' corresponds to the SOIC-16 narrow package variant when sourcing. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure thermal management aligns with the specified operating temperature limits during system design.
Selection Notes
Select this component for applications requiring transition-mode PFC with enhanced noise resilience. Compare against the UCC28061 series if automotive qualification or different pinout configurations are required. Evaluate PCB layout constraints associated with the SOIC-16 package dimensions.
Part Context
This part belongs to the UCC28063 family of power management integrated circuits focused on power factor correction. It serves as a specialized controller for improving input current shaping in switching power converters. The device integrates necessary control loops for transition-mode operation without external compensation complexity.
Replacement Considerations
The UCC28063D is a documented equivalent within the same product family offering identical functional specifications.
