Description and Introduction

Full bridge current driven vertical deflection booster The TDA4867J is a power factor correction (PFC) controller IC manufactured by PHILIPS (now NXP Semiconductors). Below are its key specifications, descriptions, and features based on factual information:  

### **Specifications:**  
- **Type:** Power Factor Correction (PFC) Controller  
- **Package:** DIP-8 (Dual In-line Package)  
- **Operating Voltage Range:** 10V to 20V  
- **Maximum Supply Voltage (VCC):** 20V  
- **Operating Frequency Range:** Adjustable (typically up to 200kHz)  
- **Output Drive Capability:** Up to 1A (for driving external MOSFETs)  
- **Standby Power Consumption:** Low (for improved efficiency)  
- **Protection Features:** Overvoltage protection (OVP), undervoltage lockout (UVLO), and overcurrent protection (OCP)  

### **Descriptions:**  
- The TDA4867J is designed for active power factor correction in switch-mode power supplies (SMPS).  
- It operates in continuous conduction mode (CCM) for high-efficiency PFC applications.  
- The IC includes an internal multiplier, error amplifier, and PWM comparator for precise control.  

### **Features:**  
- **CCM Operation:** Ensures high efficiency and low harmonic distortion.  
- **Internal Start-up Timer:** Simplifies circuit design.  
- **Zero Current Detection (ZCD):** Ensures proper switching transitions.  
- **Soft-Start Function:** Reduces inrush current during startup.  
- **Low Distortion:** Complies with IEC 1000-3-2 standards for harmonic current emissions.  

This information is based on the manufacturer's datasheet and technical documentation. For detailed application circuits and performance graphs, refer to the official datasheet.
