Description and Introduction

SIMPLE SWITCHER Power Converter High Efficiency 1A Step-Down Voltage Regulator The LM2675LD-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  
- **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:** TO-263 (DDPAK/TO-263-5)  

### **Descriptions:**  
The LM2675LD-12 is a monolithic, high-efficiency switching regulator designed for step-down (buck) voltage conversion. It integrates a 1A switch and requires minimal external components. The fixed 12V output version simplifies design while providing stable power delivery.  

### **Features:**  
- **Simple Design:** Requires only 5 external components.  
- **High Efficiency:** Uses a low ON-resistance DMOS switch.  
- **Internal Frequency Compensation:** Reduces external component count.  
- **Thermal Shutdown & Current Limiting:** Protects against overloads.  
- **Soft-Start Capability:** Minimizes inrush current.  
- **Low Power Standby Mode:** Enhances efficiency in light-load conditions.  

This regulator is suitable for applications requiring efficient power conversion, such as industrial, automotive, and consumer electronics.
