Description and Introduction

Advanced PFC/PWM Combination Controllers The UCC28511DW is a Power Factor Correction (PFC) controller manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Topology:** Continuous Conduction Mode (CCM) PFC  
- **Input Voltage Range:** 85V to 265V AC  
- **Output Voltage Range:** Adjustable (typically up to 400V DC)  
- **Switching Frequency:** Adjustable (up to 250 kHz)  
- **Operating Temperature Range:** -40°C to +105°C  
- **Package:** SOIC-16 (DW)  

### **Descriptions:**  
The UCC28511DW is a high-performance PFC controller designed for AC-DC power supplies. It ensures high power factor correction by regulating the input current waveform to match the input voltage.  

### **Features:**  
- **Average Current Mode Control:** Ensures low distortion and high power factor.  
- **Programmable Switching Frequency:** Allows optimization for efficiency and EMI performance.  
- **Soft-Start Function:** Reduces inrush current during startup.  
- **Overvoltage Protection (OVP):** Safeguards against excessive output voltage.  
- **Undervoltage Lockout (UVLO):** Ensures proper operation under low input voltage conditions.  
- **Zero-Current Detection (ZCD):** Prevents reverse recovery issues in the boost diode.  
- **Low Startup Current:** Reduces power consumption during startup.  

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