Description and Introduction

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

### **Specifications:**  
- **Input Voltage Range:** 8V to 40V  
- **Output Voltage Range:** Adjustable (1.23V to 37V)  
- **Output Current:** Up to 1A  
- **Switching Frequency:** 260 kHz (fixed)  
- **Efficiency:** Up to 92%  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** SOIC-8  

### **Descriptions:**  
The LM2671MX-ADJ is a monolithic integrated circuit that provides all active functions for a step-down (buck) switching regulator. It is designed to drive a 1A load with excellent line and load regulation. The adjustable version allows the output voltage to be set via an external resistor divider.  

### **Features:**  
- Simple and easy-to-use design  
- Requires minimal external components  
- Internal soft-start reduces inrush current  
- Thermal shutdown and current limit protection  
- Low power standby mode (shutdown pin)  
- High efficiency (up to 92%)  
- Fixed frequency PWM control  

This regulator is suitable for battery chargers, power supplies, and other applications requiring efficient step-down voltage conversion.
