### **Descriptions:**
The UCC2813N-4 is a high-performance, average-current-mode PFC controller designed for boost-type power factor correction circuits. It operates in continuous conduction mode (CCM) and provides precise control to improve power factor and reduce harmonic distortion in AC-DC power supplies.
### **Features:**
- **Average Current Mode Control:** Ensures low distortion and high power factor.
- **Low Start-Up Current:** Enables efficient operation at low power.
- **Programmable Switching Frequency:** Allows flexibility in design.
- **Overvoltage Protection (OVP):** Safeguards against excessive output voltage.
- **Undervoltage Lockout (UVLO):** Ensures proper operation within voltage limits.
- **Soft-Start Function:** Reduces inrush current during startup.
- **High-Current Totem Pole Output:** Drives external MOSFETs efficiently.
