### **Descriptions:**  
The UCC28019AD is a high-performance, continuous conduction mode (CCM) PFC controller designed for AC-DC power supplies. It improves power factor by shaping the input current to follow the input voltage, reducing harmonic distortion.  

### **Features:**  
- **Average Current Mode Control** for precise current shaping  
- **Low THD (Total Harmonic Distortion)**  
- **Internal Start-Up Timer**  
- **Overvoltage Protection (OVP)**  
- **Undervoltage Lockout (UVLO)**  
- **Programmable Soft-Start**  
- **Cycle-by-Cycle Current Limiting**  
- **Low Power Consumption**  

This controller is commonly used in power supplies for industrial, telecom, and computing applications.
