Description and Introduction

BiCMOS Power Factor Preregulator The UCC2819AD is a power factor correction (PFC) controller manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Input Voltage Range:** 4.5V to 12V  
- **Operating Frequency:** Up to 250 kHz  
- **Output Drive Current:** ±1.5A (peak)  
- **Supply Current:** 3.5 mA (typical)  
- **Package:** SOIC-16  
- **Operating Temperature Range:** -40°C to +85°C  

### **Descriptions:**  
The UCC2819AD is a high-performance, average current-mode PFC controller designed for boost-type power factor correction circuits. It features low distortion, high power factor, and precise output voltage regulation.  

### **Features:**  
- **Average Current-Mode Control:** Ensures low input current distortion.  
- **Programmable Oscillator Frequency:** Allows flexible design.  
- **Soft-Start Function:** Reduces inrush current.  
- **Overvoltage Protection (OVP):** Safeguards against output overvoltage.  
- **Undervoltage Lockout (UVLO):** Ensures proper startup conditions.  
- **Low Start-Up Current:** Minimizes power consumption.  

This information is based on the manufacturer's datasheet.
