Description and Introduction

SIMPLE SWITCHER Power Converter High Efficiency 500mA Step-Down Voltage Regulator with Features The LM2671M-3.3 is a step-down voltage regulator manufactured by National Semiconductor (NS). Below are its specifications, descriptions, and features based on factual information from Ic-phoenix technical data files:

### **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 LM2671M-3.3 is a monolithic integrated circuit that provides all the active functions for a step-down (buck) switching regulator. It is designed for easy implementation and requires minimal external components. The regulator includes a fixed-frequency oscillator, a high-efficiency power switch, and internal feedback compensation.

### **Features:**
- **Simple and Easy-to-Use Design**  
- **Internal Soft-Start** (Reduces inrush current)  
- **Low Power Standby Mode** (IQ < 50µA)  
- **Thermal Shutdown Protection**  
- **Current Limiting Protection**  
- **Wide Input Voltage Range (8V to 40V)**  
- **Fixed Output Voltage (3.3V)**  
- **High Efficiency (Up to 90%)**  
- **Requires Few External Components**  

This information is strictly based on the manufacturer's datasheet and technical documentation.
