Description and Introduction

SIMPLE SWITCHER Power Converter 150 kHz 0.5A Step-Down Voltage Regulator The LM2594HVN-12 is a step-down (buck) switching voltage regulator manufactured by ON Semiconductor (NS).  

### **Specifications:**  
- **Output Voltage:** Fixed 12V  
- **Input Voltage Range:** 4.5V to 40V (High Voltage version)  
- **Output Current:** Up to 0.5A  
- **Switching Frequency:** 150 kHz  
- **Efficiency:** Up to 80%  
- **Operating Junction Temperature:** -40°C to +125°C  
- **Package:** DIP-8 (Through-Hole)  

### **Descriptions:**  
The LM2594HVN-12 is a monolithic integrated circuit that provides all active functions for a step-down switching regulator. It is designed for easy implementation in high-efficiency buck converter applications.  

### **Features:**  
- **Fixed 12V Output** (±4% tolerance)  
- **Wide Input Voltage Range** (4.5V to 40V)  
- **Low Power Standby Mode** (IQ < 80µA)  
- **Internal Frequency Compensation**  
- **Thermal Shutdown & Current Limit Protection**  
- **Requires Minimal External Components**  

This regulator is suitable for power supply applications requiring a stable 12V output from a higher input voltage.
