Description and Introduction

SIMPLE SWITCHER 1A Step-Down Voltage Regulator The LM2575HVN-15 is a high-voltage step-down (buck) switching regulator manufactured by ON Semiconductor (NS).  

### **Specifications:**  
- **Input Voltage Range:** 4.5V to 60V  
- **Output Voltage:** Fixed 15V (±4% tolerance)  
- **Output Current:** Up to 1A  
- **Switching Frequency:** 52 kHz (typical)  
- **Efficiency:** Up to 88%  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** TO-263-5 (D2PAK)  

### **Descriptions:**  
- The LM2575HVN-15 is a monolithic integrated circuit optimized for step-down voltage regulation.  
- It simplifies power supply design with minimal external components.  
- Includes features like thermal shutdown and current limit protection.  

### **Features:**  
- **Fixed 15V Output** – No external feedback resistors needed.  
- **Wide Input Voltage Range** – Suitable for industrial and automotive applications.  
- **Low Power Standby Mode** – Consumes minimal current in shutdown.  
- **Internal Frequency Compensation** – Reduces external component count.  
- **Thermal Shutdown & Current Limit Protection** – Enhances reliability.  
- **Simple Design** – Requires only 4 external components for operation.  

This regulator is commonly used in power supplies, battery chargers, and industrial control systems.
