Description and Introduction

High Performance Power Factor Preregulator 20-SOIC 0 to 70 The **UC3855BDWTRG4** is a high-performance power factor correction (PFC) controller manufactured by **Texas Instruments (TI)**.  

### **Key Specifications:**  
- **Package:** SOIC-16 (DW)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Input Voltage Range:** Up to 600V  
- **Switching Frequency:** Adjustable up to 250kHz  
- **Driver Output Current:** ±1.5A peak  
- **Power Factor Correction:** >0.99  
- **Supply Voltage (VCC):** 12V to 25V  

### **Descriptions:**  
The UC3855BDWTRG4 is designed for **average current mode control** in power factor correction circuits, ensuring high efficiency and compliance with harmonic distortion standards (e.g., IEC 61000-3-2). It features a **multiplier/divider circuit** for precise current shaping and includes **soft-start, overvoltage protection (OVP), and undervoltage lockout (UVLO)** for robust operation.  

### **Features:**  
- **Average Current Mode Control** for improved PFC performance  
- **Programmable Switching Frequency** (up to 250kHz)  
- **Low Distortion, High Power Factor** (>0.99)  
- **Integrated High-Current Totem Pole Driver** (±1.5A)  
- **Wide Operating Voltage Range** (12V to 25V VCC)  
- **Protections:** Overvoltage, Undervoltage Lockout (UVLO), Soft-Start  
- **Low Startup Current** (<150µA)  

This IC is commonly used in **AC/DC power supplies, LED drivers, and industrial PFC applications**.
