Overview
The UCC28019ADR is an 8-pin Continuous Conduction Mode (CCM) Power Factor Correction (PFC) controller manufactured by Texas Instruments. It operates within a supply voltage range of 10 V to 21 V, with a nominal input of 15 V. The device supports a switching frequency of 68.3 kHz and functions reliably across an extended temperature range from -40°C to +125°C. Packaged in a surface-mount SOIC-8 format, it utilizes pulse width modulation technology for efficient power management.
Feature Summary
- Implements continuous conduction mode (CCM) control architecture for power factor correction applications
- Utilizes pulse width modulation (PWM) technique for precise regulation
- Designed for operation within standard industrial temperature extremes
Applications
- LED lighting systems requiring dynamic load performance optimization
- General purpose power factor correction circuits
- Power management integrated circuit designs
Procurement Notes
Verify the specific suffix 'R' confirms the reel packaging configuration distinct from tube variants. Confirm the component meets RoHS compliance standards as indicated in official specifications. Ensure the SOIC-8 package dimensions align with the target PCB footprint requirements before finalizing procurement orders.
Selection Notes
Select this component when a fixed-frequency CCM PFC solution is required. The SOIC-8 package suits surface-mount assembly processes. Consider the 68.3 kHz switching frequency for electromagnetic interference planning. Verify that the 10 V to 21 V operating voltage range matches the system's power supply capabilities.
Part Context
This part belongs to the UCC28019A series of power management ICs. It serves as a specialized controller for improving power efficiency in AC-DC conversion stages. The device complements other Texas Instruments PMIC offerings by providing dedicated PFC functionality in a compact form factor suitable for modern electronic equipment.
Replacement Considerations
The UCC28019AD is a pin-compatible alternative differing primarily in tube packaging rather than electrical function. The UCC28019AP represents a through-hole PDIP variant within the same family but is marked as obsolete.
