Description and Introduction

Universal-Input/13 or 16 W Flyback Switching Regulators The STR-A6151 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:** 85V to 265V AC  
- **Output Power:** Up to 15W  
- **Switching Frequency:** Approximately 50kHz  
- **Operating Temperature Range:** -20°C to +85°C  
- **Package Type:** TO-220F-5L (isolated type)  
- **Protection Features:** Overcurrent protection (OCP), Overvoltage protection (OVP), Thermal shutdown  

### **Descriptions:**  
- The STR-A6151 is a flyback-type switching regulator IC designed for AC/DC power supplies.  
- It integrates a high-voltage MOSFET, PWM controller, and protection circuits into a single package.  
- Suitable for applications such as adapters, LED drivers, and auxiliary power supplies.  

### **Features:**  
- Built-in high-voltage startup circuit (reduces external components).  
- Low standby power consumption.  
- Auto-restart function for fault protection.  
- Soft-start function to reduce inrush current.  
- Frequency jittering for improved EMI performance.  

This information is based solely on the manufacturer's datasheet and technical documentation.
