- **Package:** TO-220-7C (through-hole)  

### **Descriptions:**  
The TOP222G is a highly integrated offline switcher IC that combines a high-voltage MOSFET, PWM controller, and protection features in a single package. It is designed for low-power applications such as AC/DC converters, battery chargers, and standby power supplies.  

### **Features:**  
- **Integrated 700V MOSFET**  
- **Auto-restart protection** for overload, short-circuit, and open-loop conditions  
- **Frequency jittering** for reduced EMI  
- **Line undervoltage detection**  
- **Thermal shutdown** with hysteresis  
- **Soft-start** for reduced stress during startup  
- **Low power standby mode**  

This device simplifies power supply design by reducing external component count while providing high efficiency and reliability.
