Description and Introduction

SIMPLE SWITCHER Power Converter High Efficiency 1A Step-Down Voltage Regulator with Features The LM2672LDX-12 is a step-down voltage regulator manufactured by National Semiconductor (NS). Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Output Voltage:** Fixed 12V  
- **Output Current:** Up to 1A  
- **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 (LD)  

### **Descriptions:**
- The LM2672LDX-12 is a monolithic integrated circuit designed for step-down (buck) DC-DC conversion.  
- It incorporates a high-efficiency switching regulator with a fixed 12V output.  
- Suitable for applications requiring a stable 12V supply from a higher input voltage.  

### **Features:**
- **Simple Design:** Requires minimal external components.  
- **Internal Soft-Start:** Reduces inrush current.  
- **Thermal Shutdown & Current Limiting:** Protects against overloads.  
- **Low Power Standby Mode:** Enhances efficiency at light loads.  
- **High Efficiency:** Minimizes power dissipation.  

This regulator is commonly used in power supplies, industrial systems, and automotive applications.  

(Note: National Semiconductor was acquired by Texas Instruments in 2011.)
