Description and Introduction

SIMPLE SWITCHER Power Converter High Efficiency 1A Step-Down Voltage Regulator with Features The LM2672M-12 is a step-down voltage regulator manufactured by National Semiconductor (NS). Below are its specifications, descriptions, and features based on factual information from Ic-phoenix technical data files:

### **Specifications:**
- **Output Voltage:** Fixed 12V  
- **Output Current:** Up to 1A  
- **Input Voltage Range:** 8V to 40V  
- **Switching Frequency:** 260 kHz (typical)  
- **Efficiency:** Up to 92%  
- **Operating Junction Temperature Range:** -40°C to +125°C  
- **Package:** 8-Pin SOIC (M)  

### **Descriptions:**
The LM2672M-12 is a monolithic integrated circuit that provides all the active functions for a step-down (buck) switching regulator. It is designed to deliver a fixed 12V output with high efficiency and minimal external components. The regulator includes a high-efficiency NPN switch, fixed-frequency oscillator, thermal shutdown, and current limiting.

### **Features:**
- Simple and easy-to-use design  
- Requires only 5 external components  
- Internal soft-start reduces inrush current  
- Thermal shutdown protection  
- Current limiting for overload protection  
- Wide input voltage range (8V to 40V)  
- High efficiency (up to 92%)  
- Fixed-frequency PWM control  

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