Description and Introduction

SIMPLE SWITCHER High Efficiency 3A Step-Down Voltage Regulator The LM2676T-3.3 is a switching voltage regulator manufactured by National Semiconductor (NSC). Below are its specifications, descriptions, and features based on factual data:

### **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-220 (5-pin)  
- **Regulation Type:** Step-down (Buck) converter  

### **Descriptions:**  
The LM2676T-3.3 is a monolithic integrated circuit designed for step-down (buck) voltage regulation. It provides a fixed 3.3V output from an input voltage range of 8V to 40V, making it suitable for a variety of power supply applications. The device integrates a high-efficiency switching regulator with a minimal number of external components, simplifying design and reducing board space.  

### **Features:**  
- **Simple and Easy-to-Use:** Requires only 5 external components.  
- **High Efficiency:** Up to 92% efficiency, reducing heat dissipation.  
- **Internal Soft-Start:** Limits inrush current during startup.  
- **Thermal Shutdown Protection:** Prevents damage from overheating.  
- **Current Limiting Protection:** Safeguards against overcurrent conditions.  
- **Wide Input Voltage Range:** Supports 8V to 40V input.  
- **Fixed Output Voltage:** 3.3V with ±2% tolerance.  
- **Low Power Standby Mode:** Reduces power consumption when disabled.  

This information is based on the manufacturer's datasheet for the LM2676T-3.3.
