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.

Application Scenarios & Design Considerations

600kHz/1.25MHz, 2.5A, Step-up PWM DC/DC Converter

Alternative Part Number

  • TPS61085DGKR --: Boost converter with adjustable output and integrated switch, similar input/output range and function, widely available and pin-compatible in many designs.
  • AP3012KTR-G1 --: Adjustable step-up DC-DC converter with comparable current capability and switching frequency, suitable drop-in for many LM2700 applications.
  • MIC2288YD5-TR --: Compact boost regulator with adjustable output, similar voltage range and load capability, good alternative when board space is limited.
  • LT1935ES5 --: Adjustable step-up DC-DC converter with comparable input range and current capability, suitable as a drop-in functional replacement.
  • MC34063ADR2G --: Versatile adjustable boost/buck/inverting switching regulator, low cost and broadly stocked, usable where exact performance is not critical.
