Description and Introduction

SIMPLE SWITCHER? 8V to 40V, 3A Low Component Count Step-Down Regulator 7-DDPAK/TO-263 -40 to 125 The LM2676S-3.3NOPB is a step-down voltage regulator manufactured by Texas Instruments (formerly National Semiconductor, NS).  

### **Specifications:**  
- **Output Voltage:** 3.3V (fixed)  
- **Input Voltage Range:** 8V to 40V  
- **Output Current:** Up to 3A  
- **Switching Frequency:** 260 kHz (typical)  
- **Efficiency:** Up to 92%  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** TO-263-7 (D2PAK)  
- **Regulation Type:** Switching Regulator (Buck Converter)  
- **Protection Features:** Thermal shutdown, current limiting  

### **Descriptions:**  
The LM2676S-3.3NOPB is a monolithic integrated circuit that provides all necessary functions for a step-down (buck) switching regulator. It is designed for high efficiency and simplicity, requiring minimal external components.  

### **Features:**  
- Simple and easy-to-use design  
- Requires only 5 external components  
- Internal soft-start reduces inrush current  
- Low power standby mode (shutdown pin)  
- High efficiency (up to 92%)  
- Wide input voltage range (8V to 40V)  
- Fixed 3.3V output  
- Thermal shutdown and current limit protection  

This regulator is commonly used in power supply applications for industrial, automotive, and consumer electronics.
