Description and Introduction

5-Terminal, Low Dropout Voltage Dropper Type The STR9015 is a power IC manufactured by SANKEN. Below are the factual details from Ic-phoenix technical data files:

### **Specifications:**
- **Manufacturer:** SANKEN  
- **Type:** Switching Regulator IC  
- **Package:** TO-220F-5L (isolated type)  
- **Input Voltage Range:** Typically operates in offline switching power supply applications  
- **Output Voltage:** Adjustable based on external components  
- **Switching Frequency:** Fixed frequency operation (exact value depends on design)  
- **Protection Features:** Includes overcurrent protection (OCP), overvoltage protection (OVP), and thermal shutdown  

### **Descriptions:**  
The STR9015 is a high-voltage switching regulator IC designed for use in power supply circuits, particularly in AC/DC converters. It integrates a power MOSFET and control circuitry, simplifying the design of offline power supplies.  

### **Features:**  
- Built-in high-voltage startup circuit  
- Low standby power consumption  
- Soft-start function to reduce inrush current  
- Isolated package (TO-220F-5L) for improved thermal performance  
- Suitable for flyback converter topologies  

For exact electrical characteristics and application details, refer to the official SANKEN datasheet.

Application Scenarios & Design Considerations

5-Terminal, Low Dropout Voltage Dropper Type

Alternative Part Number

  • STR-A6159 --: Offline switching regulator IC in the STR-A series with similar primary-side regulation function and comparable power range, widely used as a substitute in small SMPS designs.
  • TNY267PN --: Integrated offline switcher with built-in MOSFET and controller, suitable drop-in style replacement for low-power flyback supplies where the STR9015 was used.
  • VIPER22A --: Common offline PWM switcher with integrated power MOSFET, frequently used as a functional replacement in low-power AC-DC converter circuits.
