Description and Introduction

Step-up PWM DC/DC Converter Integrated with 5 Buffers The LM2710 is a dual monolithic switching regulator manufactured by National Semiconductor (NS).  

### **Specifications:**  
- **Input Voltage Range:** 4V to 20V  
- **Output Voltage 1 (Buck Regulator):** Adjustable from 1.25V to 5.5V  
- **Output Voltage 2 (Boost Regulator):** Adjustable from 2.5V to 20V  
- **Switching Frequency:** 600 kHz (Buck), 550 kHz (Boost)  
- **Output Current:**  
  - Buck: Up to 1.5A  
  - Boost: Up to 400mA  
- **Efficiency:** Up to 90% (Buck), Up to 85% (Boost)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** 16-Pin TSSOP  

### **Descriptions:**  
The LM2710 integrates a step-down (buck) regulator and a step-up (boost) regulator in a single IC. It is designed for applications requiring multiple regulated voltages from a single input source. The buck regulator provides high-efficiency step-down conversion, while the boost regulator allows for step-up conversion.  

### **Features:**  
- **Dual Switching Regulators:** Combines buck and boost topologies.  
- **Adjustable Output Voltages:** Set via external resistors.  
- **Synchronized Switching:** Reduces noise and interference.  
- **Internal Soft-Start:** Prevents inrush current.  
- **Current Mode Control:** Improves transient response.  
- **Thermal Shutdown Protection:** Prevents overheating.  
- **Low Shutdown Current:** <1µA (typical).  

The LM2710 is suitable for battery-powered devices, portable electronics, and power management applications.
