- **Package:** MSOP-8  

### **Descriptions:**  
- The LTC3631 is a **synchronous buck regulator** with an integrated high-side and low-side power MOSFET.  
- It is designed for **high input voltage applications** with low quiescent current (30µA in Burst Mode operation).  
- Features **Burst Mode operation** for improved efficiency at light loads.  
- Includes **soft-start, current limit, and thermal shutdown** protection.  

### **Features:**  
- **Wide Input Voltage Range (4V to 60V)**  
- **High Efficiency Synchronous Operation**  
- **Adjustable Switching Frequency**  
- **Low Quiescent Current (30µA in Burst Mode)**  
- **Integrated Power MOSFETs (No External Schottky Diode Required)**  
- **Programmable Soft-Start**  
- **Thermal Shutdown Protection**  
- **Current Mode Control for Fast Transient Response**  

This regulator is suitable for **industrial, automotive, and telecom applications** requiring high efficiency and wide input voltage range.
