Description and Introduction

SIMPLE SWITCHER® 3A Step-Down Voltage Regulator The LM2576HVT5.0 is a step-down (buck) switching voltage 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% (depending on conditions)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** TO-220-5 (Through-Hole)  
- **Regulation Type:** PWM (Pulse Width Modulation)  

### **Descriptions:**  
The LM2576HVT5.0 is a monolithic integrated circuit that provides all active functions for a step-down switching regulator. It is designed for easy implementation in high-efficiency power supply designs. The device includes a fixed-frequency oscillator, a high-current switch, and a voltage reference.  

### **Features:**  
- **Simple and Easy to Use:** Requires minimal external components.  
- **Internal Current Limit and Thermal Shutdown Protection.**  
- **Low Power Standby Mode:** Typically 50 µA when shut down.  
- **Wide Input Voltage Range:** Suitable for automotive and industrial applications.  
- **Stable with Low-ESR Output Capacitors.**  
- **Available in Fixed and Adjustable Output Versions.**  

This regulator is commonly used in power supply designs for automotive, industrial, and consumer electronics applications.
