Description and Introduction

SIMPLE SWITCHER Power Converter High Efficiency 1A Step-Down Voltage Regulator with Features The LM2672M-5.0 is a step-down voltage regulator manufactured by National Semiconductor (NSC). Below are its specifications, descriptions, and features based on factual information:

### **Specifications:**
- **Output Voltage:** 5.0V (fixed)  
- **Input Voltage Range:** 8V to 40V  
- **Output Current:** Up to 1A  
- **Switching Frequency:** 260 kHz (typical)  
- **Efficiency:** Up to 90%  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** 8-Pin SOIC (M)  

### **Descriptions:**
- The LM2672M-5.0 is a monolithic integrated circuit that provides all active functions for a step-down (buck) switching regulator.  
- It is designed for simplicity and efficiency, requiring minimal external components.  
- The regulator includes a fixed-frequency oscillator, a high-efficiency switch, and internal compensation for stable operation.  

### **Features:**
- **Simple and Easy to Use:** Requires only 5 external components.  
- **High Efficiency:** Uses a low ON-resistance DMOS power switch.  
- **Internal Soft-Start:** Reduces inrush current during startup.  
- **Thermal Shutdown Protection:** Prevents damage from overheating.  
- **Short-Circuit Protection:** Includes cycle-by-cycle current limiting.  
- **Wide Input Voltage Range:** Suitable for automotive and industrial applications.  

This information is based on the manufacturer's datasheet for the LM2672M-5.0.
