Description and Introduction

High Speed Synchronous MOSFET Driver The LM2725M is a high-efficiency, synchronous step-down DC-DC controller manufactured by National Semiconductor (NS).  

### **Specifications:**  
- **Input Voltage Range:** 4.5V to 36V  
- **Output Voltage Range:** Adjustable from 0.6V to 90% of VIN  
- **Switching Frequency:** 300kHz (fixed)  
- **Output Current:** Up to 15A (with external MOSFETs)  
- **Efficiency:** Up to 95%  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** 16-Pin SOIC  

### **Descriptions:**  
The LM2725M is designed for high-current, step-down DC-DC conversion applications. It integrates a synchronous buck controller with gate drivers for external N-channel MOSFETs, enabling high efficiency and compact power supply designs.  

### **Features:**  
- **Synchronous Rectification:** Reduces power loss and improves efficiency.  
- **Adjustable Output Voltage:** Via external resistor divider.  
- **Soft-Start:** Prevents inrush current during startup.  
- **Overcurrent Protection:** Uses current-sense resistors for accurate current limiting.  
- **Thermal Shutdown:** Protects the device from overheating.  
- **Under-Voltage Lockout (UVLO):** Ensures proper operation within input voltage range.  

This information is based solely on the manufacturer's datasheet for the LM2725M.
