Description and Introduction

Vertical deflection booster The TDA4864J is a power factor correction (PFC) controller IC manufactured by PHILIPS (now NXP Semiconductors). Below are its specifications, descriptions, and features based on factual data:  

### **Specifications:**  
- **Manufacturer:** PHILIPS (NXP Semiconductors)  
- **Type:** Power Factor Correction (PFC) Controller  
- **Package:** DIP-8 (Dual In-line Package, 8 pins)  
- **Operating Voltage Range:** Typically 10V to 28V  
- **Switching Frequency:** Adjustable, typically up to 200 kHz  
- **Maximum Duty Cycle:** ~95%  
- **Current Sense Input:** Includes overcurrent protection  
- **Start-Up Current:** Low start-up current for improved efficiency  
- **Operating Temperature Range:** -40°C to +125°C  

### **Descriptions:**  
The TDA4864J is designed for active power factor correction in switch-mode power supplies (SMPS). It operates in transition mode (boundary conduction mode) to improve efficiency and reduce harmonic distortion. The IC includes features like overvoltage protection, undervoltage lockout (UVLO), and soft-start functionality.  

### **Features:**  
- **Transition Mode Operation:** Ensures high efficiency and low EMI.  
- **Integrated Boost Converter Control:** Simplifies PFC circuit design.  
- **Overvoltage Protection (OVP):** Safeguards against excessive output voltage.  
- **Undervoltage Lockout (UVLO):** Prevents operation at insufficient supply voltage.  
- **Soft-Start Function:** Reduces inrush current during startup.  
- **Zero Current Detection (ZCD):** Ensures operation in boundary conduction mode.  
- **Low Power Consumption:** Optimized for energy-efficient applications.  

This information is based on the manufacturer's datasheet and technical documentation.
