Description and Introduction

SIMPLE SWITCHER Power Converter High Efficiency 1A Step-Down Voltage Regulator The LM2675M3.3 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 92%  
- **Package:** TO-263 (D2PAK)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Protection Features:** Thermal shutdown, current limiting  

### **Descriptions:**  
The LM2675M3.3 is a monolithic integrated circuit designed for step-down (buck) voltage regulation. It provides a fixed 3.3V output with high efficiency, making it suitable for power supply applications in automotive, industrial, and consumer electronics.  

### **Features:**  
- Simple and easy-to-use design  
- Requires minimal external components  
- Internal soft-start for reduced inrush current  
- Low standby current in shutdown mode  
- High efficiency due to low dropout operation  
- Adjustable version available (LM2675)  

This regulator is ideal for applications requiring a stable 3.3V supply from higher input voltages.
