Description and Introduction

SIMPLE SWITCHER® 3A Step-Down Voltage Regulator The LM2576HVT-12 is a step-down (buck) switching regulator manufactured by ON Semiconductor (NS).  

### **Specifications:**  
- **Output Voltage:** 12V (fixed)  
- **Input Voltage Range:** 4.75V to 60V  
- **Output Current:** Up to 3A  
- **Switching Frequency:** 52 kHz  
- **Efficiency:** Up to 88%  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** TO-220 (5-pin)  
- **Regulation Type:** PWM (Pulse Width Modulation)  

### **Descriptions:**  
The LM2576HVT-12 is a monolithic integrated circuit designed for step-down voltage regulation. It simplifies power supply design by requiring minimal external components and includes features like thermal shutdown and current limiting for protection.  

### **Features:**  
- **Fixed 12V Output**  
- **3A Output Current Capability**  
- **Wide Input Voltage Range (4.75V to 60V)**  
- **Internal Frequency Compensation**  
- **Thermal Shutdown and Current Limit Protection**  
- **Low Power Standby Mode (50µA typical)**  
- **Requires Only 4 External Components**  
- **Available in TO-220 Package**
