Description and Introduction

SIMPLE SWITCHER 1A Step-Down Voltage Regulator The LM2575MX-ADJ is a step-down (buck) switching regulator manufactured by ON Semiconductor (NS).  

### **Specifications:**  
- **Input Voltage Range:** 4V to 40V  
- **Adjustable Output Voltage Range:** 1.23V to 37V  
- **Output Current:** Up to 1A  
- **Switching Frequency:** 52 kHz (fixed)  
- **Efficiency:** Up to 88%  
- **Operating Junction Temperature:** -40°C to +125°C  
- **Package:** SOIC-8 (Exposed Pad)  
- **Regulator Type:** Buck Converter  
- **Protection Features:** Thermal shutdown and current limit  

### **Descriptions:**  
The LM2575MX-ADJ is a monolithic integrated circuit that provides all active functions for a step-down switching regulator. It is designed for easy implementation and requires minimal external components. The adjustable version allows the output voltage to be set via an external resistor divider.  

### **Features:**  
- Simple and easy-to-use design  
- Requires only 4 external components  
- Internal frequency compensation  
- Low power standby mode (IQ ≈ 50 µA)  
- High efficiency compared to linear regulators  
- Wide input voltage range  
- Thermal shutdown and current limit protection  

This information is based solely on the manufacturer's datasheet.
