Description and Introduction

SIMPLE SWITCHER 5A Step-Down Voltage Regulator with Adjustable Current Limit The LM2679S-ADJ is a switching voltage regulator manufactured by National Semiconductor (NSC). Below are its specifications, descriptions, and features:

### **Specifications:**
- **Input Voltage Range:** 8V to 40V  
- **Adjustable Output Voltage:** 1.21V to 37V  
- **Output Current:** Up to 5A  
- **Switching Frequency:** 260 kHz (fixed)  
- **Efficiency:** Up to 92%  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** TO-263 (D2PAK)  
- **Regulation Type:** Buck (Step-Down)  

### **Descriptions:**
The LM2679S-ADJ is a high-efficiency, step-down switching regulator designed for applications requiring high current and adjustable output voltage. It integrates a power MOSFET switch, oscillator, and control circuitry, reducing external component count.  

### **Features:**
- **Simple Adjustable Output:** Uses two external resistors to set output voltage.  
- **High Efficiency:** Minimizes power dissipation.  
- **Internal Soft-Start:** Reduces inrush current.  
- **Thermal Shutdown & Current Limiting:** Protects against overloads.  
- **Wide Input Voltage Range:** Suitable for automotive and industrial applications.  
- **Low Power Standby Mode:** Enhances efficiency at light loads.  

This information is sourced from the manufacturer's datasheet.
