Description and Introduction

Step-up PWM DC/DC Converter Integrated with 4 Buffers The LM2711MTADJ is a switching regulator manufactured by National Semiconductor (NS).  

### **Specifications:**  
- **Input Voltage Range:** 4V to 20V  
- **Output Voltage Range:** Adjustable (via external resistors)  
- **Switching Frequency:** 300 kHz  
- **Output Current:** Up to 1A  
- **Efficiency:** Up to 90%  
- **Package:** TSSOP-16  
- **Operating Temperature Range:** -40°C to +125°C  
- **Features:**  
  - Adjustable output voltage  
  - Internal soft-start  
  - Thermal shutdown protection  
  - Current limiting  
  - Synchronization capability  

### **Descriptions and Features:**  
The LM2711MTADJ is a dual monolithic buck regulator with an adjustable output voltage. It integrates two PWM controllers, allowing for flexible power supply designs. The device operates at a fixed switching frequency of 300 kHz, reducing external component size. It includes built-in protection features such as thermal shutdown and current limiting. The adjustable output voltage is set using external resistors, making it suitable for various applications requiring precise voltage regulation.  

This regulator is commonly used in industrial, automotive, and consumer electronics applications where efficient power conversion is needed.
