Description and Introduction

SIMPLE SWITCHER Power Converter 150 kHz 0.5A Step-Down Voltage Regulator, with Features The LM2597HVN-3.3 is a step-down (buck) switching regulator manufactured by ON Semiconductor (NS).  

### **Specifications:**  
- **Input Voltage Range:** 4.5V to 60V  
- **Output Voltage:** Fixed 3.3V  
- **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-3.3 is a high-voltage, monolithic switching regulator designed for step-down voltage conversion.  
- It integrates a fixed-frequency oscillator, high-side switch, and feedback control circuitry.  
- Suitable for applications requiring high input voltage and efficient power conversion.  

### **Features:**  
- **Wide Input Voltage Range:** 4.5V to 60V  
- **Fixed 3.3V Output (±4% Tolerance)**  
- **3A Output Current Capability**  
- **Internal Frequency Compensation**  
- **Thermal Shutdown & Current Limit Protection**  
- **Low Power Standby Mode**  
- **Simple External Components Required**  
- **Available in a TO-263-5 Package**  

This regulator is commonly used in industrial, automotive, and power supply applications where high input voltage and stable 3.3V output are required.
