Description and Introduction

Power Control ICs The TDA4862 is a power factor correction (PFC) controller IC manufactured by **SIEMENS**.  

### **Specifications:**  
- **Type:** Power Factor Correction (PFC) Controller  
- **Operating Voltage Range:** Typically operates with a supply voltage of **10V to 20V**  
- **Switching Frequency:** Adjustable, typically in the range of **20kHz to 200kHz**  
- **Current Sensing:** Includes a current sense input for accurate PFC control  
- **Soft-Start Function:** Built-in to reduce inrush current  
- **Protection Features:** Overvoltage protection (OVP), undervoltage lockout (UVLO), and overcurrent protection (OCP)  
- **Package:** Typically available in **DIP-8 or SO-8** packages  

### **Descriptions and Features:**  
- Designed for **active power factor correction** in switch-mode power supplies (SMPS)  
- Implements **average current mode control** for high efficiency and low distortion  
- Suitable for **boost converter** topologies  
- Includes an **internal reference voltage** for precise regulation  
- **Low standby power consumption** for energy-efficient applications  
- Used in applications such as **AC-DC power supplies, LED drivers, and industrial power systems**  

This IC helps improve power quality by ensuring the input current waveform follows the input voltage waveform, reducing harmonic distortion and improving efficiency.
