Description and Introduction

52kHz Simple 3A Buck Regulator The LM2576-5.0WT is a step-down (buck) switching voltage regulator manufactured by Microchip Technology (formerly Micrel).  

### **Specifications:**  
- **Output Voltage:** Fixed 5V  
- **Output Current:** Up to 3A  
- **Input Voltage Range:** 4.75V to 40V  
- **Switching Frequency:** 52 kHz  
- **Efficiency:** Up to 88% (typical)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** TO-263-5 (D2PAK)  
- **Protection Features:** Thermal shutdown, current limit  

### **Descriptions:**  
The LM2576-5.0WT is a monolithic integrated circuit that provides all active functions for a step-down switching regulator. It is designed for easy implementation and requires minimal external components.  

### **Features:**  
- Simple and easy-to-use design  
- Requires only 4 external components  
- Internal frequency compensation  
- Fixed-frequency oscillator  
- Low power standby mode (IQ ≈ 50 μA)  
- High efficiency compared to linear regulators  
- Available in fixed and adjustable output versions  
- TTL shutdown capability  

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