### **Descriptions:**
The UCC2809DTR-1G4 is a high-performance, average current-mode PFC controller designed for boost-type power factor correction circuits. It provides precise control of input current shaping to achieve near-unity power factor. The device is optimized for continuous conduction mode (CCM) operation and includes features for improved efficiency and reliability in AC/DC power supplies.

### **Features:**
- **Average Current Mode Control:** Ensures low distortion input current.  
- **Programmable Switching Frequency:** Allows flexibility in design.  
- **Soft-Start Function:** Reduces inrush current during startup.  
- **Overvoltage Protection (OVP):** Safeguards against output overvoltage conditions.  
- **Undervoltage Lockout (UVLO):** Ensures proper operation within voltage range.  
- **Peak Current Limiting:** Protects against excessive current.  
- **Low Startup Current:** Enhances efficiency.  
- **SOIC-8 Package:** Compact and suitable for surface-mount applications.  

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