Description and Introduction

COLOR TV EAST-WEST CORRECTION The TEA2031A is a monolithic integrated circuit manufactured by STMicroelectronics (ST). It is designed as a high-efficiency, low standby power offline flyback converter controller for power supply applications.  

### **Specifications:**  
- **Input Voltage Range:** 85V to 265V AC  
- **Switching Frequency:** Adjustable (typically 65 kHz)  
- **Standby Power Consumption:** < 30mW  
- **Output Power Capability:** Up to 12W (depending on design)  
- **Operating Temperature Range:** -40°C to +105°C  
- **Package:** SO-8  

### **Descriptions:**  
- The TEA2031A is optimized for low standby power consumption, making it suitable for energy-efficient power supplies.  
- It operates in quasi-resonant mode for improved efficiency and reduced EMI.  
- The IC includes built-in protections such as overvoltage protection (OVP), overcurrent protection (OCP), and thermal shutdown.  

### **Features:**  
- **Quasi-Resonant Operation:** Reduces switching losses and improves efficiency.  
- **Frequency Jittering:** Minimizes EMI emissions.  
- **Auto-Restart Protection:** Safeguards against faults.  
- **Internal Startup Circuit:** Simplifies external component requirements.  
- **Green Mode Operation:** Ensures low power consumption in standby mode.  

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