Description and Introduction

Advanced Two-Phase Synchronous Triple Regulator Controller for Notebook CPUs The LM2633MTD is a switching regulator manufactured by National Semiconductor (NS). Below are the factual details about its specifications, descriptions, and features:

### **Specifications:**  
- **Input Voltage Range:** 4.5V to 30V  
- **Output Voltage Range:** Adjustable from 1.25V to 5V  
- **Output Current:** Up to 3A  
- **Switching Frequency:** 150kHz  
- **Efficiency:** Up to 90%  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package Type:** TSSOP-16  

### **Descriptions:**  
The LM2633MTD is a step-down (buck) switching regulator designed for high-efficiency power conversion. It integrates a power MOSFET and control circuitry to provide a compact solution for DC-DC conversion. The device is suitable for applications requiring high current and low output voltage with minimal external components.  

### **Features:**  
- **Integrated Power MOSFET:** Reduces external component count.  
- **Adjustable Output Voltage:** Set via external resistors.  
- **Soft-Start Function:** Prevents inrush current at startup.  
- **Overcurrent Protection:** Safeguards against excessive load conditions.  
- **Thermal Shutdown:** Protects the device from overheating.  
- **Synchronous Rectification:** Improves efficiency.  
- **Wide Input Voltage Range:** Supports various power sources.  

This information is based on the manufacturer's datasheet for the LM2633MTD.
