### **Descriptions:**  
The UCC28019ADR is designed for power factor correction (PFC) in AC/DC power supplies. It operates in continuous conduction mode (CCM) to improve efficiency and reduce input current distortion. The device features average current mode control for precise regulation and low harmonic distortion.  

### **Features:**  
- **High Power Factor (>0.99)**  
- **Low THD (Total Harmonic Distortion)**  
- **Internal Start-up Timer**  
- **Overvoltage Protection (OVP)**  
- **Undervoltage Lockout (UVLO)**  
- **Soft-Start Function**  
- **Adjustable Frequency and Current Limit**  
- **Low Standby Power Consumption**  

This device is commonly used in applications such as server power supplies, industrial power systems, and LED lighting drivers.
