Description and Introduction

General Purpose, Gated Oscillator Based, DC/DC Boost Converter 8-VSSOP -40 to 85 The LM2623MM/NOPB is a step-up DC-DC switching regulator manufactured by National Semiconductor (NSC). Below are its key specifications, descriptions, and features:

### **Specifications:**  
- **Input Voltage Range:** 0.8V to 14V  
- **Output Voltage Range:** Adjustable from 1.24V to 14V  
- **Output Current:** Up to 1.5A (switch current limit)  
- **Switching Frequency:** 300kHz (typical)  
- **Efficiency:** Up to 90%  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** 8-Pin VSSOP (MSOP)  

### **Descriptions:**  
- The LM2623MM/NOPB is a high-efficiency, low-voltage step-up DC-DC converter designed for battery-powered applications.  
- It integrates a power MOSFET and features a low startup voltage (0.8V), making it suitable for single-cell or dual-cell battery systems.  
- The device includes internal soft-start, thermal shutdown, and current limiting for protection.  

### **Features:**  
- **Wide Input Voltage Range:** Operates from 0.8V to 14V.  
- **Adjustable Output Voltage:** Set via an external resistor divider.  
- **Low Quiescent Current:** 17µA (typical) in shutdown mode.  
- **Integrated Power MOSFET:** Simplifies external circuitry.  
- **Internal Soft-Start:** Reduces inrush current.  
- **Thermal Shutdown Protection:** Prevents overheating.  
- **Current Limiting:** Protects the device and load.  

This information is based solely on the manufacturer's datasheet for the LM2623MM/NOPB.
