Description and Introduction

General Purpose, Gated Oscillator Based, DC/DC Boost Converter 8-VSSOP -40 to 85 The **LM2623MMX/NOPB** is a high-efficiency, step-up DC-DC switching regulator manufactured by **National Semiconductor (NSC)**.  

### **Key Specifications:**  
- **Input Voltage Range:** 0.8V to 14V  
- **Output Voltage Range:** Adjustable from 1.24V to 14V  
- **Maximum Output Current:** 1.2A (switch current limit)  
- **Switching Frequency:** 300kHz (typical)  
- **Efficiency:** Up to 90%  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** 10-pin MSOP (Mini Small Outline Package)  

### **Descriptions:**  
The LM2623MMX/NOPB is designed for battery-powered applications requiring a regulated output voltage higher than the input supply. It integrates a low-resistance N-channel MOSFET switch, minimizing external component count.  

### **Features:**  
- **Wide Input Voltage Range** (0.8V to 14V)  
- **Adjustable Output Voltage** (1.24V to 14V)  
- **Low Quiescent Current** (17µA typical)  
- **Internal Soft-Start** to limit inrush current  
- **Undervoltage Lockout (UVLO)**  
- **Thermal Shutdown Protection**  
- **Synchronous Rectification Capability** (for improved efficiency)  

This device is commonly used in **portable electronics, battery-powered systems, and energy harvesting applications**.
