Description and Introduction

600kHz/1.3MHz Step-up PWM DC/DC Converter 8-VSSOP -40 to 125 The LM2622MMX-ADJ/NOPB is a step-up DC-DC switching regulator manufactured by National Semiconductor (NSC).  

### **Specifications:**  
- **Input Voltage Range:** 2V to 14V  
- **Adjustable Output Voltage:** Up to 14V  
- **Switching Frequency:** 300kHz  
- **Maximum Output Current:** 1.2A (depending on input/output conditions)  
- **Efficiency:** Up to 90%  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** 8-pin VSSOP (MSOP)  

### **Descriptions:**  
The LM2622MMX-ADJ/NOPB is a high-efficiency, low-voltage, step-up DC-DC converter designed for battery-powered applications. It features an adjustable output voltage, low shutdown current, and internal soft-start to minimize inrush current.  

### **Features:**  
- **Low Start-up Voltage:** 2V  
- **Adjustable Output Voltage via External Resistors  
- **Internal N-Channel MOSFET Switch (0.25Ω typical)  
- **Low Quiescent Current:** 50µA (typical)  
- **Thermal Shutdown Protection  
- **Undervoltage Lockout (UVLO)  
- **Soft-Start Function  

This device is commonly used in portable electronics, battery-powered systems, and other applications requiring efficient voltage conversion.
