- **Low Standby Power Consumption:** <1W (typical)  
- **Operating Temperature Range:** -25°C to +125°C  
- **Package Type:** TO-3P(N)  

### **Descriptions:**  
The STRW6753 is a high-voltage switching regulator IC designed for offline power supplies. It integrates a power MOSFET, PWM controller, and protection circuits into a single package. It is commonly used in applications such as LCD/LED TVs, monitors, and other AC/DC power supplies.  

### **Features:**  
- **Built-in Power MOSFET:** Reduces external component count.  
- **Soft-Start Function:** Minimizes inrush current.  
- **Overcurrent Protection (OCP):** Safeguards against excessive current.  
- **Overvoltage Protection (OVP):** Prevents damage from high voltage.  
- **Thermal Shutdown (TSD):** Protects against overheating.  
- **Frequency Jittering:** Reduces EMI noise.  
- **Auto-Restart Function:** Recovers automatically after fault conditions.  

For detailed application circuits and performance curves, refer to the official SANKEN datasheet.
