Description and Introduction

SIMPLE SWITCHER 1A Step-Down Voltage Regulator 5-TO-220 -40 to 125 The LM2575HVT-15/NOPB is a step-down (buck) switching regulator manufactured by Texas Instruments (formerly National Semiconductor, NS).  

### **Specifications:**  
- **Output Voltage:** Fixed 15V  
- **Output Current:** Up to 1A  
- **Input Voltage Range:** 4.75V to 40V  
- **Switching Frequency:** 52 kHz (typical)  
- **Efficiency:** Up to 77% (depending on conditions)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** TO-220-5 (Through-Hole)  
- **Regulation Type:** Buck (Step-Down)  
- **Protection Features:** Thermal shutdown, current limit  

### **Descriptions:**  
The LM2575HVT-15/NOPB is a monolithic integrated circuit designed for step-down voltage regulation. It simplifies power supply design by requiring minimal external components and provides high efficiency compared to linear regulators.  

### **Features:**  
- **Fixed Output Voltage (15V)**  
- **Wide Input Voltage Range (4.75V to 40V)**  
- **1A Output Current Capability**  
- **Internal Frequency Compensation**  
- **Thermal Shutdown and Current Limit Protection**  
- **Low Power Standby Mode (IQ ~50μA typical)**  
- **Requires Only 4 External Components**  

This regulator is commonly used in industrial, automotive, and consumer applications where efficient step-down voltage conversion is needed.
