Description and Introduction

600kHz/1.25MHz, 2.5A, Step-up PWM DC/DC Converter The LM2700MT-ADJ is a step-up DC-DC converter manufactured by National Semiconductor (NS). Below are its key specifications, descriptions, and features:

### **Specifications:**  
- **Input Voltage Range:** 2.6V to 14V  
- **Adjustable Output Voltage:** Up to 22V  
- **Output Current:** Up to 1A  
- **Switching Frequency:** 600 kHz  
- **Efficiency:** Up to 90%  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** TO-263-5 (D2PAK)  

### **Descriptions:**  
The LM2700MT-ADJ is a high-efficiency, step-up DC-DC converter designed for applications requiring regulated higher voltages from lower input sources. It integrates a power MOSFET and provides adjustable output voltage via an external resistor divider.  

### **Features:**  
- **Adjustable Output Voltage** via external resistors  
- **Internal Power MOSFET** (0.25Ω typical RDS(ON))  
- **Low Shutdown Current** (<1µA)  
- **Soft-Start Function** to limit inrush current  
- **Thermal Shutdown Protection**  
- **Current Limiting and Over-Temperature Protection**  

This device is suitable for battery-powered systems, LCD bias supplies, and portable electronics.
