Description and Introduction

OFF-LINE QUASI-RESONANT FLYBACK SWITCHING REGULATORS The STRF6652 is a power switch IC manufactured by SANKEN. Below are its key specifications, descriptions, and features based on available information:  

### **Specifications:**  
- **Input Voltage Range:** 85V to 265V AC  
- **Output Power:** Up to 100W (depending on design)  
- **Switching Frequency:** Fixed at 100kHz  
- **Operating Temperature Range:** -20°C to +85°C  
- **Package Type:** TO-220F (5-pin)  
- **Built-in Features:**  
  - High-voltage MOSFET (650V)  
  - PWM controller  
  - Overcurrent protection (OCP)  
  - Overvoltage protection (OVP)  
  - Thermal shutdown  

### **Descriptions:**  
The STRF6652 is a hybrid IC combining a power MOSFET and a PWM controller in a single package. It is designed for offline switch-mode power supplies (SMPS) and is commonly used in applications like AC/DC adapters, LED drivers, and power supplies for consumer electronics.  

### **Features:**  
- **Integrated Design:** Combines a high-voltage MOSFET and control circuitry.  
- **Low Standby Power Consumption:** Suitable for energy-efficient designs.  
- **Protection Functions:** Includes OCP, OVP, and thermal shutdown for reliability.  
- **Fixed Frequency Operation:** Simplifies external circuit design.  
- **Wide Input Voltage Range:** Supports universal AC input (85V–265V).

Application Scenarios & Design Considerations

OFF-LINE QUASI-RESONANT FLYBACK SWITCHING REGULATORS

Alternative Part Number

  • STR-F6652 --: Same STR-F series offline switching regulator with identical pinout and power rating, widely used as a direct substitute for STRF6652.
  • STR-F6653 --: Higher power variant in the same STR-F family, pin-compatible and often used when the original is unavailable.
  • STR-W6756 --: Similar Sanken offline quasi-resonant regulator with comparable voltage/current ratings, usable as a functional replacement with minor circuit checks.
  • STRF6654 --: Higher-power variant in the same STR-F family with compatible pinout and control scheme, suitable when slightly more output power is needed.
  • STRF6454 --: Lower-power member of the same STR-F series sharing the same package and application circuit, usable in less demanding loads.
