Description and Introduction

Advanced PFC/PWM Combination Controllers The UCC28511N is a Power Factor Correction (PFC) controller manufactured by Texas Instruments (TI). Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Control Method:** Average Current Mode Control  
- **Input Voltage Range:** 85V to 265V AC  
- **Output Voltage Range:** Up to 400V DC  
- **Switching Frequency:** Adjustable up to 250kHz  
- **Operating Temperature Range:** -40°C to 85°C  
- **Package Type:** 16-Pin PDIP (Plastic Dual In-Line Package)  

### **Descriptions:**
- The UCC28511N is designed for high-performance active PFC applications.  
- It integrates a boost converter controller with power factor correction to improve efficiency and reduce harmonic distortion.  
- Suitable for offline power supplies, industrial systems, and lighting applications.  

### **Features:**
- **Power Factor Correction (PFC):** Ensures near-unity power factor.  
- **Average Current Mode Control:** Provides stable and accurate current regulation.  
- **Programmable Switching Frequency:** Allows optimization for efficiency and EMI performance.  
- **Overvoltage Protection (OVP):** Safeguards against excessive output voltage.  
- **Undervoltage Lockout (UVLO):** Ensures proper operation under low input voltage conditions.  
- **Soft-Start Function:** Reduces inrush current during startup.  
- **Low Startup Current:** Minimizes power consumption during initial operation.  

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