Description and Introduction

SIMPLE SWITCHER Power Converter High Efficiency 1A Step-Down Voltage Regulator The LM2675LDX-5.0 is a step-down voltage regulator manufactured by National Semiconductor (NS). Below are its specifications, descriptions, and features:  

### **Specifications:**  
- **Output Voltage:** 5.0V (fixed)  
- **Input Voltage Range:** 8V to 40V  
- **Output Current:** Up to 1A  
- **Switching Frequency:** 260 kHz (typical)  
- **Efficiency:** Up to 92%  
- **Operating Junction Temperature:** -40°C to +125°C  
- **Package:** TO-263 (D2PAK)  
- **Regulation:** ±2% (over line and load conditions)  
- **Protection Features:** Thermal shutdown, current limiting  

### **Descriptions:**  
The LM2675LDX-5.0 is a monolithic integrated circuit that provides all active functions for a step-down (buck) switching regulator. It is designed to drive a 1A load with high efficiency, minimizing the need for external components.  

### **Features:**  
- Simple and easy-to-use design  
- Requires only 5 external components  
- Internal soft-start reduces inrush current  
- Low power standby mode (IQ < 50 µA)  
- High efficiency (up to 92%)  
- Fixed-frequency oscillator (260 kHz)  
- Thermal shutdown and current limit protection  
- TO-263 package for improved thermal performance  

This information is based on the manufacturer's datasheet.
