Description and Introduction

SIMPLE SWITCHER Power Converter High Efficiency 1A Step-Down Voltage Regulator The LM2675LDX-3.3 is a step-down voltage regulator manufactured by National Semiconductor (NS).  

### **Specifications:**  
- **Output Voltage:** 3.3V (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:** TO-263 (D2PAK)  

### **Descriptions:**  
The LM2675LDX-3.3 is a monolithic integrated circuit that provides a step-down (buck) switching regulator function. It is designed for high-efficiency power conversion and requires minimal external components.  

### **Features:**  
- Simple and easy-to-use design  
- Requires only 5 external components  
- Internal soft-start for reduced inrush current  
- Thermal shutdown and current limit protection  
- Low power standby mode  
- Adjustable output version available (LM2675)  

This regulator is suitable for applications requiring a stable 3.3V supply from a higher input voltage, such as industrial, automotive, and consumer electronics.
