Description and Introduction

SIMPLE SWITCHER 1A Step-Down Voltage Regulator 5-DDPAK/TO-263 -40 to 125 The LM2575HVS-5.0/NOPB is a monolithic integrated circuit from Texas Instruments (formerly National Semiconductor, NS3) designed for step-down (buck) switching regulator applications.  

### **Specifications:**  
- **Input Voltage Range:** 4V to 60V  
- **Output Voltage:** Fixed 5V  
- **Output Current:** Up to 1A  
- **Switching Frequency:** 52 kHz  
- **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 LM2575HVS-5.0/NOPB is a high-voltage version of the LM2575 series, capable of handling input voltages up to 60V. It simplifies power supply design by requiring minimal external components and provides a fixed 5V output.  

### **Features:**  
- **Fixed 5V Output** (±4% tolerance)  
- **Wide Input Voltage Range** (4V to 60V)  
- **1A Load Current Capability**  
- **Internal Frequency Compensation**  
- **Low Power Standby Mode** (50μA typical)  
- **Thermal Shutdown & Current Limiting Protection**  
- **Requires Only 4 External Components**  
- **Available in a TO-263-5 Package**  

This device is commonly used in industrial, automotive, and consumer applications requiring efficient step-down voltage regulation.
