Description and Introduction

Micropower Step-up DC/DC Converter with 550mA Peak Current Limit The LM2704MF-ADJ is a step-up DC-DC converter manufactured by National Semiconductor (NS). Below are its specifications, descriptions, and features:

### **Specifications:**  
- **Input Voltage Range:** 2.6V to 7V  
- **Adjustable Output Voltage:** Up to 15V  
- **Output Current:** Up to 400mA (dependent on input/output conditions)  
- **Switching Frequency:** 1MHz (typical)  
- **Efficiency:** Up to 90%  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** SOT-23-5  

### **Descriptions:**  
The LM2704MF-ADJ is a high-efficiency, low-noise, step-up DC-DC converter designed for battery-powered applications. It integrates a power switch and provides a regulated output voltage from a low input supply. The adjustable output version allows flexibility in setting the desired voltage via external resistors.  

### **Features:**  
- **Adjustable Output Voltage** (via external resistors)  
- **Internal Power MOSFET Switch** (reduces external component count)  
- **Low Quiescent Current:** 40µA (typical)  
- **Soft-Start Function** (prevents inrush current)  
- **Thermal Shutdown Protection**  
- **Current Limiting Protection**  
- **Small Footprint** (SOT-23-5 package)  

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