Description and Introduction

1 The UCC2809P-1 is a power factor correction (PFC) controller manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Input Voltage Range:** 7.5V to 12V (VCC)  
- **Operating Frequency:** Up to 500 kHz  
- **Output Drive Current:** ±1.5A (peak)  
- **Duty Cycle Range:** 0% to 100%  
- **Error Amplifier Bandwidth:** 5 MHz  
- **Soft-Start Function:** Yes  
- **Package:** 8-Pin PDIP (Plastic Dual In-Line Package)  
- **Operating Temperature Range:** -40°C to +85°C  

### **Descriptions:**  
The UCC2809P-1 is a high-performance, average current mode PFC controller designed for boost converters. It provides power factor correction by shaping the input current waveform to match the input voltage, improving efficiency and reducing harmonic distortion.  

### **Features:**  
- **Average Current Mode Control** for accurate current shaping  
- **Low Distortion** input current waveform  
- **Programmable Oscillator Frequency**  
- **Overvoltage Protection (OVP)**  
- **Undervoltage Lockout (UVLO)**  
- **Peak Current Limiting**  
- **Soft-Start Function** for controlled startup  

This device is commonly used in AC/DC power supplies, LED drivers, and industrial power systems requiring power factor correction.
