Description and Introduction

PFC Controller for low to medium power applications requiring compliance with IEC 1000-3-2 The UCC28051P is a power factor correction (PFC) controller manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Input Voltage Range:** 85 VAC to 265 VAC  
- **Operating Frequency:** Adjustable up to 250 kHz  
- **Output Voltage Range:** Up to 450 VDC  
- **Control Method:** Average Current Mode Control  
- **Package:** 8-Pin PDIP (Plastic Dual In-Line Package)  
- **Operating Temperature Range:** -40°C to 105°C  
- **Supply Voltage (VCC):** 12 V to 17 V (typical)  
- **Standby Power Consumption:** <1 W  

### **Descriptions:**  
The UCC28051P is designed for continuous conduction mode (CCM) power factor correction (PFC) applications. It improves power factor by shaping the input current to follow the input voltage waveform, reducing harmonic distortion and improving efficiency.  

### **Features:**  
- **Low Distortion:** Minimizes input current harmonics  
- **Internal Start-Up Timer:** Ensures controlled soft-start  
- **Overvoltage Protection (OVP):** Safeguards against excessive output voltage  
- **Undervoltage Lockout (UVLO):** Prevents operation at insufficient supply voltage  
- **Zero Power Detection:** Reduces standby power consumption  
- **Programmable Switching Frequency:** Allows optimization for efficiency and EMI performance  

This information is based solely on the manufacturer's specifications for the UCC28051P.
