Description and Introduction

600kHz/1.25MHz, 2.5A, Step-up PWM DC/DC Converter The LM2700MTX-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 24V  
- **Output Current:** Up to 1.2A (switch current limit)  
- **Switching Frequency:** 600 kHz (typical)  
- **Efficiency:** Up to 85%  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** TO-263 (D2PAK)  

### **Descriptions:**
The LM2700MTX-ADJ is a high-efficiency, step-up DC-DC converter designed for applications requiring a regulated output voltage higher than the input supply. It integrates a power switch, oscillator, and control circuitry, making it suitable for battery-powered and portable devices.

### **Features:**
- **Adjustable Output Voltage** via external resistors  
- **Internal Power MOSFET Switch** (1.2A current limit)  
- **Low Shutdown Current** (<1µA)  
- **Soft-Start Function** to reduce inrush current  
- **Thermal Shutdown Protection**  
- **Wide Input Voltage Range** (2.6V to 14V)  
- **Compact Surface-Mount Package (D2PAK)**  

This information is sourced from the manufacturer's datasheet.

Description and Introduction

600kHz/1.25MHz, 2.5A, Step-up PWM DC/DC Converter The LM2700MTX-ADJ is a step-up DC-DC converter manufactured by National Semiconductor (NS).  

### **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-263-7 (DDPAK/TO-263)  
- **Internal Soft-Start:** Reduces inrush current  
- **Low Shutdown Current:** <1µA  

### **Descriptions and Features:**  
- **Boost Converter:** Converts a lower input voltage to a higher adjustable output voltage.  
- **Adjustable Output:** Uses an external resistor divider to set the output voltage.  
- **Current Mode Control:** Improves transient response and loop stability.  
- **Integrated Power Switch:** Simplifies design and reduces external components.  
- **Thermal Shutdown Protection:** Prevents damage from overheating.  
- **Under-Voltage Lockout (UVLO):** Ensures proper operation within input voltage range.  
- **Synchronous Rectification (Optional):** Can be used for higher efficiency.  

The LM2700MTX-ADJ is designed for applications requiring efficient step-up voltage conversion, such as battery-powered devices, LCD bias supplies, and portable electronics.
