Description and Introduction

PFC Controller for low to medium power applications requiring compliance with IEC 1000-3-2 The UCC28051DR 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:  

### **Manufacturer:** Texas Instruments (TI)  
### **Part Number:** UCC28051DR  

### **Description:**  
The UCC28051DR is a high-performance, average current-mode PFC controller designed for boost-type pre-regulators. It operates in continuous conduction mode (CCM) and is optimized for power supplies requiring power factor correction.  

### **Key Features:**  
- **Average Current-Mode Control:** Ensures low distortion input current.  
- **Wide Operating Range:** Input voltage range from 85 VAC to 265 VAC.  
- **High Switching Frequency:** Up to 250 kHz.  
- **Low Start-Up Current:** Typically 50 µA.  
- **Programmable Oscillator Frequency:** Adjustable via external resistor.  
- **Soft-Start Function:** Reduces inrush current.  
- **Overvoltage Protection (OVP):** Safeguards against output overvoltage.  
- **Undervoltage Lockout (UVLO):** Ensures proper operation under low-voltage conditions.  
- **Zero-Current Detection (ZCD):** Prevents reverse recovery losses.  
- **Low Power Consumption:** Typically 5 mA operating current.  
- **Package:** SOIC-8 (DR package).  

### **Applications:**  
- AC-DC power supplies  
- LED lighting drivers  
- Industrial power systems  
- Telecom power supplies
