### **Descriptions:**  
The UCC2808AQDR-1Q1 is designed for high-performance power factor correction in AC/DC power supplies. It operates in continuous conduction mode (CCM) and uses average current mode control to achieve near-unity power factor.  

### **Features:**  
- **Average Current Mode Control:** Ensures low distortion input current.  
- **Low Start-up and Operating Current:** Enhances efficiency.  
- **Programmable Oscillator Frequency:** Allows flexibility in design.  
- **Overvoltage Protection (OVP):** Safeguards against output overvoltage.  
- **Undervoltage Lockout (UVLO):** Ensures proper operation under low supply conditions.  
- **Soft-Start Function:** Reduces inrush current during startup.  
- **High Noise Immunity:** Robust performance in noisy environments.  

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