Description and Introduction

SIMPLE SWITCHER Power Converter 150 kHz 0.5A Step-Down Voltage Regulator The LM2597MX-ADJ is a step-down (buck) switching regulator manufactured by National Semiconductor (NS).  

### **Specifications:**  
- **Input Voltage Range:** 4.5V to 40V  
- **Adjustable Output Voltage Range:** 1.23V to 37V  
- **Output Current:** Up to 3A  
- **Switching Frequency:** 150 kHz (fixed)  
- **Efficiency:** Up to 92%  
- **Operating Junction Temperature:** -40°C to +125°C  
- **Package:** SOIC-8  

### **Descriptions:**  
The LM2597MX-ADJ is a monolithic integrated circuit that provides all active functions for a step-down (buck) switching regulator. It is designed to drive a 3A load with excellent line and load regulation. The device requires minimal external components and includes a fixed-frequency oscillator, thermal shutdown, and current-limit protection.  

### **Features:**  
- Adjustable output voltage version (LM2597-ADJ)  
- 3A output current capability  
- Wide input voltage range (4.5V to 40V)  
- Internal frequency compensation  
- Thermal shutdown and current-limit protection  
- Available in a compact SOIC-8 package  
- Low standby current (50 μA typical)
