Description and Introduction

SIMPLE SWITCHER Power Converter High Efficiency 500mA Step-Down Voltage Regulator with Features The LM2671MX-3.3 is a step-down voltage regulator manufactured by National Semiconductor (NSC).  

### **Specifications:**  
- **Output Voltage:** 3.3V (fixed)  
- **Input Voltage Range:** 8V to 40V  
- **Output Current:** Up to 500mA  
- **Switching Frequency:** 260 kHz (typical)  
- **Efficiency:** Up to 90%  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** SOIC-8  

### **Descriptions:**  
The LM2671MX-3.3 is a monolithic integrated circuit that provides all active functions for a step-down (buck) switching regulator. It is designed for easy implementation and high efficiency, requiring minimal external components.  

### **Features:**  
- Simple and easy-to-use design  
- Requires only 5 external components  
- Internal soft-start for reduced inrush current  
- Thermal shutdown and current limit protection  
- Low standby current in shutdown mode  
- Adjustable output version available (LM2671M-ADJ)  

This regulator is commonly used in power supply applications requiring efficient step-down conversion.
