Description and Introduction

5-Bit Programmable Synchronous Buck Regulator Controller The LM2636MTC is a synchronous buck regulator manufactured by National Semiconductor (NS).  

### **Specifications:**  
- **Input Voltage Range:** 4.5V to 24V  
- **Output Voltage Range:** Adjustable from 1.25V to 5.5V  
- **Output Current:** Up to 6A  
- **Switching Frequency:** 300kHz  
- **Efficiency:** Up to 95%  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** 28-pin TSSOP (Thermal Enhanced)  

### **Descriptions:**  
The LM2636MTC is a high-efficiency, step-down DC-DC converter designed for high-current applications. It integrates synchronous rectification to minimize power loss and improve efficiency. The device includes features like soft-start, overcurrent protection, and thermal shutdown for reliable operation.  

### **Features:**  
- **Synchronous Rectification** for high efficiency  
- **Adjustable Output Voltage** via external resistors  
- **Soft-Start Function** to limit inrush current  
- **Overcurrent Protection** with hiccup mode  
- **Thermal Shutdown** for overtemperature protection  
- **Wide Input Voltage Range** (4.5V to 24V)  
- **High Switching Frequency (300kHz)** for reduced external component size  

This information is based on the manufacturer's datasheet.
