Description and Introduction

SIMPLE SWITCHER Power Converter High Efficiency 1A Step-Down Voltage Regulator The LM2675MX-3.3 is a step-down voltage regulator manufactured by National Semiconductor (NS). Below are its specifications, descriptions, and features based on Ic-phoenix technical data files:  

### **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 96%  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** SOIC-8  

### **Descriptions:**  
The LM2675MX-3.3 is a monolithic integrated circuit that provides all the active functions for a step-down (buck) switching regulator. It is designed to drive a 1A load with excellent line and load regulation. The device includes a fixed-frequency oscillator, thermal shutdown, current limiting, and an on/off control input.  

### **Features:**  
- Simple and easy-to-use design  
- Requires minimal external components  
- Internal soft-start for reduced inrush current  
- Thermal shutdown and current limit protection  
- Adjustable output version available (LM2675)  
- Low standby current in shutdown mode  
- High efficiency (up to 96%)  

This information is strictly factual and derived from the manufacturer's datasheet.
