Description and Introduction

BiCMOS Power Factor Preregulator The UCC2818DW is a high-performance, BiCMOS power factor correction (PFC) controller manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Input Voltage Range:** 4.5V to 12V  
- **Operating Frequency:** Adjustable up to 250 kHz  
- **Output Drive Current:** ±1.5A (peak)  
- **PWM Control Method:** Average Current Mode  
- **Power Factor Correction:** >0.99  
- **Package:** SOIC-16 (DW)  
- **Operating Temperature Range:** -40°C to 85°C  

### **Descriptions:**  
The UCC2818DW is designed for power factor correction in AC/DC power supplies. It features an average current mode control architecture, ensuring low distortion and high power factor. The device includes an internal oscillator, error amplifier, and multiplier for precise regulation.  

### **Features:**  
- **Average Current Mode Control** for low input current distortion  
- **Programmable Oscillator Frequency** with synchronization capability  
- **Soft-Start Function** to reduce inrush current  
- **Overvoltage Protection (OVP)** and **Undervoltage Lockout (UVLO)**  
- **Low Startup Current** (<150 µA)  
- **High Noise Immunity** due to BiCMOS technology  

This controller is commonly used in power supplies, LED drivers, and industrial applications requiring high-efficiency PFC.
