Description and Introduction

8-Pin Continuous Conduction Mode (CCM) PFC Controller 8-SOIC The UCC28019DRG4 is a PFC (Power Factor Correction) controller manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Type:** Continuous Conduction Mode (CCM) PFC Controller  
- **Input Voltage Range:** 85 V to 265 V (AC)  
- **Output Voltage Range:** Adjustable (typically up to 400 V DC)  
- **Switching Frequency:** Adjustable (up to 300 kHz)  
- **Operating Temperature Range:** -40°C to +105°C  
- **Package:** SOIC-8  
- **Control Method:** Average Current Mode Control  
- **Supply Voltage (VCC):** 10.5 V to 21 V  
- **Peak Gate Drive Current:** ±1.5 A  

### **Descriptions:**  
The UCC28019DRG4 is designed for high-efficiency power factor correction in AC/DC power supplies. It operates in continuous conduction mode (CCM) to minimize input current distortion and improve power factor. The device features an average current mode control scheme for precise current shaping and low THD (Total Harmonic Distortion).  

### **Features:**  
- **High Power Factor (>0.99)**  
- **Low THD (<5%)**  
- **Programmable Switching Frequency**  
- **Internal Start-Up Timer**  
- **Overvoltage Protection (OVP)**  
- **Undervoltage Lockout (UVLO)**  
- **Soft-Start Function**  
- **Cycle-by-Cycle Current Limiting**  

This IC is commonly used in applications such as power supplies, LED drivers, and industrial power systems requiring high power factor correction.
