**Descriptions:**  
The KA5H0265RC is a high-voltage power switch IC designed for offline flyback converters. It integrates a high-voltage MOSFET and PWM controller, making it suitable for compact power supply designs.  

**Features:**  
- Built-in 650V MOSFET  
- Internal soft-start for reduced stress  
- Auto-restart protection for overload and short-circuit conditions  
- Low standby power consumption  
- Cycle-by-cycle current limiting  
- Thermal shutdown protection  
- Internal high-voltage startup circuit  

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