Description and Introduction

SIMPLE SWITCHER 1A Step-Down Voltage Regulator The LM2575HVMX-5.0 is a step-down (buck) switching voltage regulator manufactured by ON Semiconductor (NS).  

### **Specifications:**  
- **Output Voltage:** 5.0V (fixed)  
- **Input Voltage Range:** 4.5V to 60V  
- **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)  
- **Regulation Type:** Buck (Step-Down)  
- **Protection Features:** Thermal shutdown, current limit  

### **Descriptions:**  
The LM2575HVMX-5.0 is a monolithic integrated circuit that provides all active functions for a step-down switching regulator. It is designed for easy implementation in various power supply applications, offering high efficiency and reliable performance.  

### **Features:**  
- Simple and easy-to-use design  
- Requires minimal external components  
- Internal frequency compensation  
- Fixed-frequency oscillator  
- Low standby current (50 µA typical)  
- Soft-start capability  
- TTL shutdown capability  
- High efficiency compared to linear regulators  
- Thermal shutdown and current limit protection  

This regulator is commonly used in industrial, automotive, and consumer electronics applications where a stable 5V output is required from a higher input voltage.
