Description and Introduction

OFF-LINE QUASI-RESONANT FLYBACK SWITCHING REGULATORS The STRF6652 is a power switch IC manufactured by Sanken Electric. Here are its key specifications, descriptions, and features:

### **Specifications:**  
- **Input Voltage Range:** 85V to 265V AC  
- **Output Power:** Up to 120W (depends on application)  
- **Switching Frequency:** Fixed at 100kHz  
- **Standby Power Consumption:** <1W  
- **Operating Temperature Range:** -20°C to +85°C  
- **Package:** TO-220F (5-pin)  

### **Descriptions:**  
- Designed for switch-mode power supply (SMPS) applications.  
- Integrates a high-voltage MOSFET, PWM controller, and protection circuits.  
- Suitable for offline power supplies in TVs, monitors, and other consumer electronics.  

### **Features:**  
- Built-in soft-start function for reduced inrush current.  
- Overcurrent protection (OCP) and overvoltage protection (OVP).  
- Auto-restart mode for fault recovery.  
- Low EMI noise due to frequency jittering.  

For detailed application notes, refer to the official Sanken datasheet.
