Description and Introduction

Full-Mold, Separate Excitation Switching Type The part **SI-8090S** is manufactured by **SanKen**. Below are the specifications, descriptions, and features based on the available knowledge:

### **Specifications:**  
- **Type:** High-voltage switching power supply IC  
- **Input Voltage Range:** 85V to 265V AC  
- **Output Power:** Up to 12W (depending on design)  
- **Switching Frequency:** Typically around 100kHz  
- **Standby Power Consumption:** Low (typically <100mW)  
- **Protection Features:** Overcurrent protection (OCP), overvoltage protection (OVP), thermal shutdown  
- **Package Type:** SIP (Single In-line Package)  

### **Descriptions:**  
The **SI-8090S** is a high-efficiency switching power supply IC designed for AC/DC converters in applications such as adapters, LED drivers, and auxiliary power supplies. It integrates a high-voltage MOSFET and PWM controller, reducing external component count.  

### **Features:**  
- Built-in high-voltage startup circuit  
- Low standby power consumption  
- Frequency jittering for reduced EMI  
- Auto-restart protection for fault conditions  
- Wide input voltage range (85V–265V AC)  
- Optimized for flyback converter topologies  

For exact performance characteristics, refer to the official **SanKen datasheet** for the **SI-8090S**.
