Description and Introduction

52kHz Simple 3A Buck Regulator The LM2576WT is a step-down (buck) switching regulator manufactured by MIC (Micro Integrated Circuits).  

### **Specifications:**  
- **Input Voltage Range:** 4V to 40V  
- **Output Voltage Options:** 3.3V, 5V, 12V, 15V, or adjustable (1.23V to 37V)  
- **Output Current:** Up to 3A  
- **Switching Frequency:** 52 kHz (fixed)  
- **Efficiency:** Up to 88%  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** TO-263-5 (D2PAK)  
- **Protection Features:** Thermal shutdown and current limit  

### **Descriptions:**  
The LM2576WT is a monolithic integrated circuit that simplifies the design of step-down switching regulators. It requires minimal external components and provides high efficiency, making it suitable for various power supply applications.  

### **Features:**  
- Simple and easy-to-use design  
- Requires only 4 external components  
- Internal frequency compensation  
- Low power standby mode (IQ ≈ 50 μA)  
- TTL shutdown capability  
- Soft-start function to reduce inrush current  

This information is based on the manufacturer's datasheet. For detailed application notes, refer to the official documentation.
