Description and Introduction

OFF-LINE SWITCHING REGULATORS - WITH BIPOLAR SWITCHING TRANSISTOR The STRS5707 is a power switching regulator IC manufactured by SANKEN. Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:  

### **Specifications:**  
- **Input Voltage Range:** 8V to 40V  
- **Output Voltage:** Adjustable (typically 5V to 35V)  
- **Output Current:** Up to 3A  
- **Switching Frequency:** 100kHz (typical)  
- **Efficiency:** Up to 90%  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package Type:** TO-220 (5-pin)  

### **Descriptions:**  
- The STRS5707 is a step-down (buck) switching regulator designed for high-efficiency power conversion.  
- It integrates a power MOSFET, PWM controller, and protection circuits into a single package.  
- Suitable for automotive, industrial, and consumer electronics applications.  

### **Features:**  
- Built-in power MOSFET for simplified design  
- Overcurrent protection (OCP)  
- Thermal shutdown protection  
- Soft-start function to reduce inrush current  
- Adjustable output voltage via external resistors  
- Low standby current consumption  

For exact performance characteristics, refer to the official datasheet from SANKEN.

Application Scenarios & Design Considerations

OFF-LINE SWITCHING REGULATORS - WITH BIPOLAR SWITCHING TRANSISTOR

Alternative Part Number

  • STR-W6756 --: Same Sanken STR series offline switching regulator with integrated MOSFET, similar power handling and control scheme, commonly used as a direct substitute in SMPS designs.
  • ICE3B0565 --: Integrated power management IC with built-in CoolMOS switch, comparable voltage/current ratings and flyback topology, widely used as a cross for Sanken STR regulators.
  • TOP258PN --: Offline switcher in TO-220 package with integrated high-voltage MOSFET, similar power range and flyback application, a common alternative when Sanken parts are unavailable.
  • STR-A6259H --: Similar offline PWM controller with integrated MOSFET, suitable for low-power AC-DC supplies and often cross-referenced for STRS-series parts.
