### **Descriptions:**  
The KA1M0380RBYDTU is a high-voltage, current-mode PWM controller designed for offline flyback converters. It integrates a high-voltage power MOSFET and control circuitry, making it suitable for low-power AC/DC applications.  

### **Features:**  
- Built-in 800V power MOSFET  
- Current-mode PWM control  
- Low standby power consumption  
- Overvoltage protection (OVP)  
- Overload protection (OLP)  
- Thermal shutdown protection  
- Auto-restart mode for fault conditions  
- Low startup current (< 30 µA)  

This IC is commonly used in power adapters, chargers, and auxiliary power supplies.
