### **Descriptions:**  
The KA5M0265RYDTU 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, LED drivers, and auxiliary power supplies.  

### **Features:**  
- **Integrated High-Voltage Startup:** Eliminates the need for an external startup resistor.  
- **Low Standby Power Consumption:** Improves energy efficiency.  
- **Frequency Jittering:** Reduces EMI noise.  
- **Soft-Start Function:** Prevents inrush current at startup.  
- **Auto-Restart Protection:** Recovers automatically after fault conditions.  
- **Green Mode Operation:** Enhances efficiency at light loads.  

(Note: FAIRCHILD is likely a typo; the correct manufacturer name is **Fairchild Semiconductor**.)
