Description and Introduction

SIMPLE SWITCHER 1A Step-Down Voltage Regulator The LM2575HVN-ADJ is a high-voltage adjustable output version of the LM2575 series monolithic switching regulator from National Semiconductor (NS).  

### **Specifications:**  
- **Input Voltage Range:** 4.75V to 60V  
- **Output Voltage Range:** Adjustable from 1.23V to 57V  
- **Output Current:** Up to 1A  
- **Switching Frequency:** 52 kHz (fixed)  
- **Efficiency:** Up to 88%  
- **Operating Junction Temperature:** -40°C to +125°C  
- **Package:** TO-263-5 (D2PAK)  

### **Descriptions:**  
The LM2575HVN-ADJ is a step-down (buck) switching regulator that simplifies power supply design with a minimal number of external components. It features internal frequency compensation and a fixed-frequency oscillator.  

### **Features:**  
- **Adjustable Output Voltage** (set via external resistors)  
- **Thermal Shutdown and Current Limit Protection**  
- **Low Power Standby Mode** (IQ ≈ 50 µA)  
- **Wide Input Voltage Range** (up to 60V)  
- **Requires Only 4 External Components**  
- **Stable with Low-ESR Output Capacitors**  

This device is commonly used in industrial, automotive, and battery-powered applications requiring efficient voltage regulation.
