Description and Introduction

PFC Controller for low to medium power applications requiring compliance with IEC 61000-3-2 8-SOIC -40 to 105 The UCC28051DG4 is a power factor correction (PFC) controller manufactured by Texas Instruments (TI). Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:

### **Specifications:**  
- **Manufacturer:** Texas Instruments (TI)  
- **Part Number:** UCC28051DG4  
- **Type:** Power Factor Correction (PFC) Controller  
- **Package:** SOIC-8  
- **Operating Temperature Range:** -40°C to 105°C  
- **Input Voltage Range:** 4.5V to 12V  
- **Switching Frequency:** Adjustable (typically up to 250kHz)  
- **Control Method:** Average Current Mode Control  
- **Maximum Duty Cycle:** 95%  
- **Start-Up Current:** < 150µA  
- **Supply Current (Operating):** 5mA (typical)  

### **Descriptions:**  
The UCC28051DG4 is a high-performance, continuous conduction mode (CCM) PFC controller designed for AC/DC power supplies. It ensures near-unity power factor by shaping the input current waveform to match the input voltage. It is suitable for applications like power supplies, LED drivers, and industrial systems requiring compliance with power quality standards.  

### **Features:**  
- **Average Current Mode Control:** Ensures low distortion and high power factor.  
- **Low Start-Up Current:** Reduces power consumption during standby.  
- **Programmable Switching Frequency:** Allows optimization for efficiency and EMI performance.  
- **Overvoltage Protection (OVP):** Safeguards against output overvoltage conditions.  
- **Undervoltage Lockout (UVLO):** Ensures proper operation within voltage limits.  
- **Soft-Start Function:** Reduces inrush current during startup.  
- **Peak Current Limiting:** Protects against excessive current conditions.  

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