Description and Introduction

SIMPLE SWITCHER Power Converter High Efficiency 1A Step-Down Voltage Regulator with Features The LM2672N-ADJ is a switching regulator manufactured by National Semiconductor (NSC). Below are its specifications, descriptions, and features:

### **Specifications:**
- **Input Voltage Range:** 8V to 40V  
- **Adjustable Output Voltage Range:** 1.21V to 37V  
- **Output Current:** Up to 1A  
- **Switching Frequency:** 260 kHz (fixed)  
- **Efficiency:** Up to 90%  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** TO-220 (7-pin)  

### **Descriptions:**
- The LM2672N-ADJ is a step-down (buck) switching voltage regulator.  
- It provides a highly efficient solution for DC-DC conversion.  
- The adjustable output version allows flexibility in setting the desired voltage.  
- Includes built-in frequency compensation and a fixed-frequency oscillator.  

### **Features:**
- **Simple Design:** Requires minimal external components.  
- **Internal Soft-Start:** Reduces inrush current during startup.  
- **Thermal Shutdown & Current Limit Protection:** Enhances reliability.  
- **Low Power Standby Mode:** Improves efficiency at light loads.  
- **High Efficiency:** Minimizes power dissipation.  

This information is based on the manufacturer's datasheet.

Description and Introduction

SIMPLE SWITCHER Power Converter High Efficiency 1A Step-Down Voltage Regulator with Features The LM2672N-ADJ is a step-down voltage regulator manufactured by National Semiconductor (NS).  

### **Specifications:**  
- **Input Voltage Range:** 8V to 40V  
- **Adjustable Output Voltage:** 1.23V to 37V  
- **Output Current:** Up to 1A  
- **Switching Frequency:** 260 kHz (fixed)  
- **Efficiency:** Up to 90%  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** TO-220 (5-pin)  
- **Protection Features:** Thermal shutdown, current limiting  

### **Descriptions:**  
The LM2672N-ADJ is a monolithic integrated circuit that provides all active functions for a step-down (buck) switching regulator. It is designed for high-efficiency power conversion with minimal external components. The adjustable output version allows flexibility in setting the desired output voltage using an external resistor divider.  

### **Features:**  
- Simple and easy-to-use design  
- Requires only 5 external components  
- High efficiency (up to 90%)  
- Wide input voltage range (8V to 40V)  
- Adjustable output voltage (1.23V to 37V)  
- Internal soft-start reduces inrush current  
- Thermal shutdown and current limit protection  
- TO-220 package for easy mounting  

This regulator is suitable for applications such as power supplies, battery chargers, and industrial systems.
