Description and Introduction

BiCMOS Power Factor Preregulator The UCC2819D is a power factor correction (PFC) controller manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Topology:** Continuous Conduction Mode (CCM)  
- **Control Method:** Average Current Mode  
- **Operating Frequency:** Adjustable up to 250 kHz  
- **Input Voltage Range:** 85 V to 265 V AC  
- **Output Voltage Regulation:** Adjustable (typically 385 V DC)  
- **Supply Voltage (VCC):** 10 V to 17 V  
- **Start-Up Current:** 150 µA (typical)  
- **Operating Current:** 5 mA (typical)  
- **Peak Gate Drive Current:** ±1.5 A  
- **Error Amplifier Bandwidth:** 5 MHz  
- **Package:** SOIC-16  

### **Descriptions:**  
The UCC2819D is designed for high-performance power factor correction in AC/DC power supplies. It operates in continuous conduction mode (CCM) and uses average current mode control to achieve near-unity power factor. It includes features like soft-start, overvoltage protection (OVP), and undervoltage lockout (UVLO).  

### **Features:**  
- **Average Current Mode Control** for improved power factor  
- **Low Distortion & High Efficiency**  
- **Programmable Switching Frequency**  
- **Soft-Start Function**  
- **Overvoltage Protection (OVP)**  
- **Undervoltage Lockout (UVLO)**  
- **Low Start-Up & Operating Current**  
- **High-Current Totem Pole Output Driver**  

This information is based on the manufacturer's datasheet for the UCC2819D.

Description and Introduction

BiCMOS Power Factor Preregulator The UCC2819D is a power factor correction (PFC) controller manufactured by Texas Instruments (TI) and Burr-Brown (BB).  

### **Specifications:**  
- **Input Voltage Range:** 4.5V to 12V  
- **Operating Frequency:** Up to 250kHz  
- **Output Drive Current:** ±1.5A (peak)  
- **Package:** SOIC-16  
- **Control Method:** Average Current Mode  
- **Features Soft-Start**  
- **Undervoltage Lockout (UVLO)**  
- **Overvoltage Protection (OVP)**  

### **Descriptions:**  
The UCC2819D is designed for high-performance power factor correction in AC-DC power supplies. It operates in continuous conduction mode (CCM) and provides precise average current control to improve power factor and reduce harmonic distortion.  

### **Features:**  
- **Average Current Mode Control** for improved power factor  
- **Programmable Oscillator Frequency**  
- **Low Start-Up Current** (<150µA)  
- **Peak Current Limiting**  
- **Internal Voltage Reference** (7.5V)  
- **Wide Operating Temperature Range** (-40°C to +105°C)  

This information is based on the manufacturer's datasheet.
