Description and Introduction

SIMPLE SWITCHER Power Converter 150 kHz 0.5A Step-Down Voltage Regulator, with Features The LM2597HVN-5.0 is a step-down (buck) switching regulator manufactured by ON Semiconductor (NS).  

### **Specifications:**  
- **Input Voltage Range:** 4.5V to 60V  
- **Output Voltage:** Fixed 5.0V  
- **Output Current:** Up to 3A  
- **Switching Frequency:** 150 kHz  
- **Efficiency:** Up to 92%  
- **Operating Junction Temperature:** -40°C to +125°C  
- **Package:** TO-263-5 (D2PAK)  

### **Descriptions:**  
The LM2597HVN-5.0 is a high-voltage, step-down DC-DC converter designed for efficient power conversion in a wide range of applications. It integrates a fixed-frequency oscillator, a high-side switch, and control circuitry to provide a stable 5V output.  

### **Features:**  
- **Wide Input Voltage Range:** Supports 4.5V to 60V input  
- **Fixed 5V Output (±4% Accuracy)**  
- **3A Output Current Capability**  
- **Internal Frequency Compensation**  
- **Thermal Shutdown and Current Limit Protection**  
- **Low Power Standby Mode (IQ ~50µA when disabled)**  
- **Simple External Components Required**  

This regulator is commonly used in industrial, automotive, and power supply applications requiring high input voltage and efficient step-down conversion.
