Description and Introduction

Micropower Step-up DC/DC Converter with 150mA Peak Current Limit The LM2705MFX-ADJ is a step-up DC-DC converter manufactured by National Semiconductor (NS). Below are the key specifications, descriptions, and features based on factual information:

### **Specifications:**  
- **Input Voltage Range:** 2.6V to 7V  
- **Adjustable Output Voltage:** Up to 20V  
- **Output Current:** Up to 1A (depending on input/output conditions)  
- **Switching Frequency:** 600kHz (typical)  
- **Efficiency:** Up to 90%  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** SOT-23-5  

### **Descriptions:**  
The LM2705MFX-ADJ is a high-efficiency, step-up DC-DC converter designed for battery-powered applications. It integrates a power switch and provides a regulated output voltage that can be adjusted using external resistors. The device is optimized for low-voltage input applications and is commonly used in portable electronics, LCD bias supplies, and LED drivers.

### **Features:**  
- **Adjustable Output Voltage** (via external resistors)  
- **Internal Power MOSFET Switch** (minimizes external components)  
- **Low Quiescent Current:** 1.1mA (typical)  
- **Soft-Start Function** (reduces inrush current)  
- **Thermal Shutdown Protection**  
- **Short-Circuit Protection**  

This information is based solely on the manufacturer’s datasheet and technical documentation.
