- **Package:** 10-Pin MSOP  

### **Descriptions:**  
The LM2622MMX-ADJ is a high-efficiency, step-up DC-DC switching regulator designed for battery-powered applications. It features an adjustable output voltage and can operate with very low input voltages, making it suitable for portable devices.  

### **Features:**  
- **Wide Input Voltage Range:** Supports operation from 2V to 14V.  
- **Adjustable Output Voltage:** Set via external resistors.  
- **Low Quiescent Current:** 40µA (typical) in shutdown mode.  
- **Internal Soft-Start:** Reduces inrush current.  
- **Over-Temperature Protection:** Ensures safe operation.  
- **Synchronous Rectification:** Improves efficiency.  

This information is based on the manufacturer's datasheet. For detailed application notes, refer to the official documentation.
