Description and Introduction

Integrated Power Supply 1A DC-DC Converter The LM2825N-ADJ is a DC-DC converter manufactured by National Semiconductor (NS). Below are its specifications, descriptions, and features:

### **Specifications:**  
- **Input Voltage Range:** 4.5V to 30V  
- **Output Voltage Range:** Adjustable from 1.23V to 20V  
- **Output Current:** Up to 1A  
- **Switching Frequency:** 100kHz (fixed)  
- **Efficiency:** Up to 80%  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** 24-pin DIP (Dual In-line Package)  

### **Descriptions:**  
The LM2825N-ADJ is a step-down (buck) switching regulator that integrates a power switch, control circuitry, and protection features into a single IC. It is designed for efficient voltage conversion in applications requiring adjustable output voltage.  

### **Features:**  
- **Integrated Power Switch:** Simplifies design by eliminating the need for an external MOSFET.  
- **Adjustable Output:** Set via external resistors.  
- **Thermal Shutdown:** Protects the IC from overheating.  
- **Current Limiting:** Prevents damage from excessive load currents.  
- **Low Dropout Operation:** Maintains regulation even when the input voltage is close to the output.  
- **Soft-Start Function:** Reduces inrush current during startup.  

This information is based on the manufacturer's datasheet. For detailed application notes, refer to the official documentation.
