### **Specifications:**  
- **Input Voltage Range:** 4.5V to 52V  
- **Output Voltage Range:** 0.7V to 90% of VIN  
- **Switching Frequency:** Adjustable from 50kHz to 600kHz  
- **Maximum Duty Cycle:** 90%  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** VSON-8 (DRB)  

### **Descriptions:**  
The TPS40040DRBRG4 is a high-performance, wide-input-voltage synchronous buck controller designed for DC-DC converter applications. It supports N-channel MOSFETs and provides adjustable switching frequency for optimized efficiency and component size.  

### **Features:**  
- **Wide Input Voltage Range:** Suitable for industrial and automotive applications.  
- **Adjustable Frequency:** Allows optimization for efficiency and component size.  
- **Synchronous Rectification:** Improves efficiency by reducing power loss.  
- **Soft-Start Function:** Prevents inrush current during startup.  
- **Undervoltage Lockout (UVLO):** Ensures proper operation under low input voltage conditions.  
- **Thermal Shutdown:** Protects the device from overheating.  
- **Lead-Free and RoHS Compliant.**
