Description and Introduction

OFF-LINE QUASI-RESONANT FLYBACK SWITCHING REGULATORS The STR-F6672 is a power supply control IC manufactured by Sanken Electric. Here are its key specifications, descriptions, and features:

### **Specifications:**  
- **Input Voltage Range:** Up to 650V (for high-voltage applications).  
- **Output Power:** Suitable for power supplies up to 200W (depending on design).  
- **Switching Frequency:** Fixed-frequency operation (typically around 50-100kHz).  
- **Standby Power Consumption:** Low standby power capability.  
- **Protection Features:** Overcurrent protection (OCP), overvoltage protection (OVP), and thermal shutdown.  

### **Descriptions:**  
- The STR-F6672 is a hybrid IC combining a power MOSFET and a control circuit in a single package.  
- Designed for switch-mode power supplies (SMPS) in TVs, monitors, and other electronic devices.  
- Operates in quasi-resonant mode for improved efficiency.  

### **Features:**  
- **Built-in MOSFET:** High-voltage power MOSFET integrated into the IC.  
- **Soft Start Function:** Reduces inrush current during startup.  
- **Auto-Restart Protection:** Automatically recovers after fault conditions.  
- **Low EMI:** Quasi-resonant operation minimizes electromagnetic interference.  
- **Compact Package:** Typically in a TO-220 or similar package for heat dissipation.  

This IC is commonly used in offline power supplies for consumer electronics.
