Description and Introduction

SIMPLE SWITCHER Power Converter High Efficiency 500mA Step-Down Voltage Regulator The LM2674N-ADJ is a switching voltage regulator manufactured by National Semiconductor (NS). Below are its key specifications, descriptions, and features:  

### **Specifications:**  
- **Input Voltage Range:** 8V to 40V  
- **Output Voltage Range:** Adjustable from 1.21V to 37V  
- **Output Current:** Up to 500mA  
- **Switching Frequency:** 260 kHz (fixed)  
- **Efficiency:** Up to 90%  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** TO-220 (5-pin)  

### **Descriptions:**  
- The LM2674N-ADJ is a step-down (buck) switching regulator with an adjustable output voltage.  
- It integrates a high-efficiency switching regulator with a fixed-frequency oscillator, reducing the need for external components.  
- Designed for simplicity, it requires minimal external components for operation.  

### **Features:**  
- **Adjustable Output Voltage** via external resistors.  
- **High Efficiency** due to low dropout operation.  
- **Internal Soft-Start** to reduce inrush current.  
- **Thermal Shutdown and Current Limit Protection** for enhanced reliability.  
- **Wide Input Voltage Range** suitable for various applications.  

This information is based on the manufacturer's datasheet.
