Description and Introduction

SIMPLE SWITCHER Power Converter High Efficiency 500mA Step-Down Voltage Regulator The LM2674MX-5.0 is a switching voltage regulator manufactured by National Semiconductor (NS).  

### **Specifications:**  
- **Output Voltage:** 5.0V (fixed)  
- **Output Current:** Up to 500mA  
- **Input Voltage Range:** 8V to 40V  
- **Switching Frequency:** 260 kHz (typical)  
- **Efficiency:** Up to 90%  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** SOIC-8  
- **Regulation Type:** Step-Down (Buck Converter)  
- **Protection Features:** Thermal shutdown, current limiting  

### **Descriptions:**  
The LM2674MX-5.0 is a monolithic integrated circuit designed for step-down (buck) voltage regulation. It provides a fixed 5.0V output with high efficiency, making it suitable for power supply applications in automotive, industrial, and consumer electronics.  

### **Features:**  
- Simple-to-use, requires minimal external components  
- Internal soft-start reduces inrush current  
- Low standby current in shutdown mode  
- Adjustable output version available (LM2674M-ADJ)  
- Thermal shutdown protection  
- Current limiting for overload protection  

This regulator is ideal for applications requiring a stable 5V supply from a higher input voltage.
