### **Descriptions:**  
The UCC2813-4 is a high-performance PFC controller designed for continuous conduction mode operation. It provides power factor correction in AC/DC power supplies, improving efficiency and reducing harmonic distortion. The device includes features such as voltage feedforward, average current mode control, and a precision reference for stable operation.  

### **Features:**  
- **Average Current Mode Control** – Ensures low harmonic distortion.  
- **Voltage Feedforward Compensation** – Improves line transient response.  
- **Programmable Switching Frequency** – Up to 250 kHz.  
- **Low Start-Up Current** – Reduces power consumption during startup.  
- **Overvoltage Protection (OVP)** – Protects against output overvoltage conditions.  
- **Soft-Start Function** – Minimizes inrush current.  
- **High-Current Totem Pole Output** – Supports MOSFET or IGBT drivers.  

This information is based solely on the manufacturer's datasheet and technical documentation.
