Description and Introduction

SIMPLE SWITCHER Power Converter High Efficiency 1A Step-Down Voltage Regulator with Features The LM2672M-ADJ is a step-down voltage regulator manufactured by National Semiconductor (NSC).  

### **Specifications:**  
- **Input Voltage Range:** 8V to 40V  
- **Adjustable Output Voltage:** 1.21V to 37V  
- **Output Current:** Up to 1A  
- **Switching Frequency:** 260 kHz (typical)  
- **Efficiency:** Up to 92%  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** SOIC-8  

### **Descriptions:**  
The LM2672M-ADJ is a monolithic integrated circuit that provides all active functions for a step-down (buck) switching regulator. It features high efficiency, requiring only a few external components. The adjustable version allows the output voltage to be set using external resistors.  

### **Features:**  
- Simple and easy-to-use design  
- Requires minimal external components  
- Internal soft-start reduces inrush current  
- Thermal shutdown and current limit protection  
- Low standby current (50 µA typical in shutdown mode)  
- TTL shutdown capability  

This regulator is commonly used in power supply applications requiring efficient step-down conversion.
