### **Descriptions:**  
The KA5H0380RYDTU 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 compact power supply designs.  

### **Features:**  
- Built-in high-voltage MOSFET (800V, 3A)  
- Current-mode control for improved transient response  
- Low standby power consumption  
- Overvoltage protection (OVP)  
- Overload protection (OLP)  
- Thermal shutdown protection  
- Auto-restart function for fault conditions  
- Soft-start for reduced inrush current  

This IC is commonly used in AC/DC adapters, LED drivers, and auxiliary power supplies.  

(Note: Always refer to the official datasheet for precise details.)
