### **Descriptions:**  
The KA5H0265RCTU is a high-voltage PWM controller designed for offline power supply applications. It integrates a high-voltage startup circuit, reducing external component count. It is optimized for flyback converters in AC/DC adapters and auxiliary power supplies.  

### **Features:**  
- Built-in high-voltage startup circuit  
- Low standby power consumption  
- Internal soft-start function  
- Cycle-by-cycle current limiting  
- Auto-restart protection for fault conditions  
- Under-voltage lockout (UVLO)  
- Low EMI noise due to frequency jittering  

This information is based on Fairchild Semiconductor's datasheet for the KA5H0265RCTU.
