- **Efficiency:** Up to 95%  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** TO-263-7 (DDPAK/TO-263)  
- **Protection Features:** Thermal shutdown, current limiting, and under-voltage lockout (UVLO)  

### **Descriptions:**  
The LM22679TJE-ADJ/NOPB is a step-down (buck) switching regulator designed for high-efficiency power conversion. It integrates a high-side N-channel MOSFET and offers adjustable output voltage via an external resistor divider.  

### **Features:**  
- **Adjustable Output Voltage** via external resistors  
- **Wide Input Voltage Range** (4.5V to 42V)  
- **High Efficiency** (up to 95%)  
- **Integrated MOSFET** for reduced external components  
- **Fixed 500 kHz Switching Frequency**  
- **Thermal Shutdown and Current Limit Protection**  
- **Under-Voltage Lockout (UVLO)** for reliable operation  
- **Low Quiescent Current** (3.5 mA typical)  

This regulator is suitable for industrial, automotive, and general-purpose power supply applications.
