Description and Introduction

SIMPLE SWITCHER Power Converter 150 kHz 0.5A Step-Down Voltage Regulator The LM2597N-ADJ is a switching voltage regulator manufactured by National Semiconductor (NS). Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:

### **Specifications:**  
- **Input Voltage Range:** 4.5V to 40V  
- **Output Voltage Range:** Adjustable from 1.23V to 37V  
- **Output Current:** Up to 3A  
- **Switching Frequency:** 150 kHz (fixed)  
- **Efficiency:** Up to 88%  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package Type:** TO-220-5 (through-hole)  

### **Descriptions:**  
- The LM2597N-ADJ is a step-down (buck) switching regulator that provides a highly efficient solution for DC-DC voltage conversion.  
- It includes an adjustable output version, allowing users to set the desired output voltage using external resistors.  
- Designed for simplicity, it requires minimal external components for operation.  

### **Features:**  
- **Adjustable Output Voltage** (via external resistors)  
- **3A Output Current Capability**  
- **Internal Frequency Compensation**  
- **Thermal Shutdown and Current Limit Protection**  
- **Low Power Standby Mode** (when disabled)  
- **Wide Input Voltage Range** (4.5V to 40V)  
- **High Efficiency** (up to 88%)  

This information is based solely on the manufacturer's datasheet and technical documentation.
