Description and Introduction

Advanced Two-Phase Synchronous Triple Regulator Controller for Notebook CPUs The LM2633MTDX is a switching regulator IC manufactured by National Semiconductor (NSC).  

### **Specifications:**  
- **Input Voltage Range:** 4.5V to 30V  
- **Output Voltage:** Adjustable (1.25V to 5V)  
- **Output Current:** Up to 3A  
- **Switching Frequency:** 260kHz (typical)  
- **Efficiency:** Up to 90%  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** TSSOP-20  

### **Descriptions:**  
The LM2633MTDX is a high-efficiency, step-down DC-DC converter designed for applications requiring high current and low output voltage. It integrates a power MOSFET and control circuitry, simplifying power supply design.  

### **Features:**  
- **Adjustable Output Voltage** via external resistors  
- **Internal Soft-Start** to reduce inrush current  
- **Overcurrent and Thermal Protection**  
- **Synchronous Rectification** for improved efficiency  
- **Low Dropout Operation** for extended battery life  
- **Wide Input Voltage Range** for versatile applications  

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