Description and Introduction

5-Bit Programmable Synchronous Buck Regulator Controller The LM2636MTCX is a switching regulator IC manufactured by National Semiconductor (NSC). Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Manufacturer:** National Semiconductor (NSC)  
- **Type:** Switching Regulator  
- **Topology:** Step-Down (Buck)  
- **Input Voltage Range:** 4V to 24V  
- **Output Voltage Range:** Adjustable (0.8V to 5.5V)  
- **Output Current:** Up to 6A  
- **Switching Frequency:** 300kHz  
- **Efficiency:** Up to 95%  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** TSSOP-28 (Thermally Enhanced)  

### **Descriptions:**
The LM2636MTCX is a high-efficiency synchronous buck regulator designed for high-current, low-voltage applications. It integrates power MOSFETs and control circuitry to provide a compact solution for DC-DC conversion.  

### **Features:**
- **Integrated Power MOSFETs** – Reduces external component count.  
- **Adjustable Output Voltage** – Set via external resistors.  
- **Current Mode Control** – Ensures stable operation with fast transient response.  
- **Soft-Start Function** – Prevents inrush current at startup.  
- **Overcurrent & Thermal Protection** – Safeguards the device under fault conditions.  
- **Synchronous Rectification** – Improves efficiency.  
- **Low Dropout Operation** – Maintains regulation even at low input-output differentials.  

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