Description and Introduction

5-Bit Programmable Synchronous Buck Regulator Controller [Not recommended for new designs] The LM2635M is a synchronous buck regulator manufactured by National Semiconductor (NS). Below are the factual details from Ic-phoenix technical data files:  

### **Specifications:**  
- **Input Voltage Range:** 4.5V to 30V  
- **Output Voltage Range:** Adjustable from 1.2V to 28V  
- **Output Current:** Up to 5A  
- **Switching Frequency:** 150kHz (fixed)  
- **Efficiency:** Up to 95%  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** 16-Pin SOIC (M)  

### **Descriptions:**  
The LM2635M is a high-efficiency, step-down DC-DC converter designed for applications requiring high output current with tight voltage regulation. It integrates a synchronous rectifier to improve efficiency and reduce external component count.  

### **Features:**  
- **Synchronous Rectification:** Enhances efficiency by reducing power loss.  
- **Adjustable Output Voltage:** Set via external resistors.  
- **Under-Voltage Lockout (UVLO):** Ensures proper operation when input voltage is insufficient.  
- **Thermal Shutdown:** Protects the device from overheating.  
- **Soft-Start:** Reduces inrush current during startup.  
- **Current Limit Protection:** Safeguards against excessive load currents.  

This information is strictly based on the manufacturer's datasheet and specifications.
