Description and Introduction

SIMPLE SWITCHER 1A Step-Down Voltage Regulator The LM2575HVSX-ADJ is a step-down (buck) switching regulator manufactured by ON Semiconductor (NS).  

### **Specifications:**  
- **Input Voltage Range:** 4V to 60V  
- **Adjustable Output Voltage Range:** 1.23V to 57V  
- **Output Current:** Up to 1A  
- **Switching Frequency:** 52 kHz (fixed)  
- **Efficiency:** Up to 88% (depending on conditions)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** TO-263-5 (D2PAK)  

### **Descriptions:**  
- The LM2575HVSX-ADJ is a monolithic integrated circuit that provides all active functions for a step-down switching regulator.  
- It features an adjustable output voltage version, allowing flexibility in design.  
- Designed for simplicity and ease of use, requiring minimal external components.  

### **Features:**  
- **Wide Input Voltage Range:** Supports 4V to 60V input.  
- **Adjustable Output Voltage:** Set via external resistors.  
- **Internal Frequency Compensation:** Simplifies circuit design.  
- **Thermal Shutdown & Current Limit Protection:** Enhances reliability.  
- **Low Power Standby Mode:** Reduces power consumption when not in use.  
- **High Efficiency:** Minimizes heat dissipation.  

This regulator is commonly used in power supply applications, battery chargers, and industrial systems requiring efficient voltage conversion.
