Description and Introduction

SIMPLE SWITCHER 1A Step-Down Voltage Regulator The LM2575HVN-5.0 is a step-down (buck) switching regulator manufactured by ON Semiconductor (NS).  

### **Specifications:**  
- **Output Voltage:** 5.0V (fixed)  
- **Input Voltage Range:** 4.75V to 60V (high-voltage version)  
- **Output Current:** Up to 1A  
- **Switching Frequency:** 52 kHz (fixed)  
- **Efficiency:** Up to 88%  
- **Operating Junction Temperature:** -40°C to +125°C  
- **Package:** TO-263-5 (D2PAK)  

### **Descriptions:**  
The LM2575HVN-5.0 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. The device includes a fixed-frequency oscillator, a high-efficiency switch, and internal feedback compensation.  

### **Features:**  
- **Fixed 5.0V Output**  
- **Wide Input Voltage Range (4.75V to 60V)**  
- **1A Output Current Capability**  
- **Internal Frequency Compensation**  
- **Thermal Shutdown & Current Limit Protection**  
- **Low Power Standby Mode (IQ ~50µA)**  
- **Simple and Easy-to-Use Design**  
- **Available in a TO-263-5 Package**  

This regulator is commonly used in power supply applications, battery chargers, and industrial systems requiring high-voltage step-down conversion.
