Description and Introduction

SIMPLE SWITCHER® 3A Step-Down Voltage Regulator The LM2576HVSX-ADJ is a step-down (buck) switching regulator manufactured by ON Semiconductor (NS).  

### **Specifications:**  
- **Input Voltage Range:** 4V to 60V  
- **Adjustable Output Voltage:** 1.23V to 57V  
- **Output Current:** 3A  
- **Switching Frequency:** 52 kHz (fixed)  
- **Efficiency:** Up to 88%  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** TO-263-5 (D2PAK)  
- **Protection Features:** Thermal shutdown, current limiting  

### **Descriptions:**  
The LM2576HVSX-ADJ is a monolithic switching regulator IC designed for step-down voltage regulation. It simplifies power supply design by requiring minimal external components and provides high efficiency. The adjustable version allows for a wide range of output voltages using an external resistor divider.  

### **Features:**  
- **Simple and Easy to Design:** Requires few external components.  
- **High Efficiency:** Reduces power dissipation.  
- **Wide Input Voltage Range:** Suitable for industrial and automotive applications.  
- **Internal Frequency Compensation:** Enhances stability.  
- **Thermal Shutdown and Current Limit Protection:** Improves reliability.  
- **Low Power Standby Mode:** Reduces power consumption when disabled.  

This regulator is commonly used in power supplies, battery chargers, and other applications requiring efficient DC-DC conversion.
