- **Package:** SO PowerPAD-8  
- **Regulation Type:** Step-Down (Buck)  
- **Protection Features:** Thermal shutdown, current limit, and under-voltage lockout (UVLO)  

### **Descriptions:**  
The LM22674MRX-ADJ/NOPB is a high-efficiency, step-down DC-DC converter designed for industrial, automotive, and general-purpose applications. It integrates a high-side N-channel MOSFET and provides a simple, compact solution for voltage regulation.  

### **Features:**  
- **Wide Input Voltage Range:** Supports 4.5V to 42V input  
- **Adjustable Output Voltage:** Set via external resistors  
- **High Efficiency:** Up to 95% with integrated MOSFET  
- **Fixed Frequency Operation:** 500 kHz for predictable noise performance  
- **Thermal Protection:** Prevents overheating  
- **Current Limit Protection:** Safeguards against excessive current  
- **Under-Voltage Lockout (UVLO):** Ensures proper operation under low input voltage conditions  
- **Compact Package:** SO PowerPAD-8 for efficient thermal dissipation  

This regulator is suitable for applications requiring stable, efficient power conversion in harsh environments.
