Description and Introduction

SIMPLE SWITCHER® 3A Step-Down Voltage Regulator The LM2576HVS-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  
- **Output Current:** Up to 3A  
- **Switching Frequency:** 52 kHz (typical)  
- **Efficiency:** Up to 88%  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** TO-263-5 (D2PAK)  
- **Regulation Type:** PWM (Pulse Width Modulation)  
- **Protection Features:** Thermal shutdown, current limiting  

### **Descriptions:**  
The LM2576HVS-5.0 is a monolithic integrated circuit designed for step-down voltage regulation. It simplifies power supply design by requiring a minimal number of external components. It is suitable for high-voltage applications due to its wide input range.  

### **Features:**  
- **Simple and Easy-to-Use** – Requires few external components.  
- **High Efficiency** – Uses a fixed-frequency PWM control scheme.  
- **Wide Input Voltage Range** – Supports operation from 4.75V to 60V.  
- **Thermal Shutdown & Current Limiting** – Protects the device from overheating and overcurrent conditions.  
- **Low Power Standby Mode** – Consumes minimal current when disabled.  
- **Stable with Low-ESR Capacitors** – Works with electrolytic capacitors.  

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