Description and Introduction

Vertical deflection booster The TDA4863 is a power factor correction (PFC) controller IC manufactured by **Infineon Technologies**.  

### **Specifications:**  
- **Input Voltage Range:** 85 V to 265 V (AC)  
- **Output Voltage:** Typically 400 V (DC)  
- **Switching Frequency:** Adjustable (typically around 100 kHz)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** P-DSO-8 (PowerSO-8)  
- **Control Method:** Transition Mode (TM) PFC for high efficiency  
- **Supply Voltage (VCC):** Up to 30 V  
- **Current Sense Input:** Integrated for accurate current regulation  

### **Descriptions:**  
The TDA4863 is designed for **active power factor correction** in switch-mode power supplies (SMPS). It operates in **transition mode (boundary conduction mode)** to optimize efficiency while minimizing switching losses. The IC includes features for **soft-start, overvoltage protection (OVP), and undervoltage lockout (UVLO)**.  

### **Features:**  
- **High Power Factor (>0.99)**  
- **Low THD (Total Harmonic Distortion)**  
- **Integrated Startup Timer**  
- **Zero Current Detection (ZCD)** for transition mode operation  
- **Overvoltage Protection (OVP)**  
- **Undervoltage Lockout (UVLO)**  
- **Adjustable Output Voltage**  
- **Low Standby Power Consumption**  

This IC is commonly used in **LED drivers, AC-DC adapters, and industrial power supplies** requiring high efficiency and compliance with power quality standards.
