Description and Introduction

High Speed Synchronous MOSFET Driver The LM2726M is a high-efficiency, synchronous step-down DC-DC converter manufactured by National Semiconductor (NS).  

### **Specifications:**  
- **Input Voltage Range:** 4.5V to 20V  
- **Output Voltage Range:** Adjustable from 0.6V to 18V  
- **Output Current:** Up to 3A  
- **Switching Frequency:** 300kHz  
- **Efficiency:** Up to 95%  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** 8-Pin SOIC  

### **Descriptions:**  
The LM2726M is designed for high-performance power conversion applications, providing a compact and efficient solution for step-down voltage regulation. It integrates synchronous rectification to minimize power loss and improve efficiency.  

### **Features:**  
- **Synchronous Buck Converter:** Reduces power dissipation by replacing the external Schottky diode.  
- **Adjustable Output Voltage:** Set via external resistors.  
- **Internal Soft-Start:** Prevents inrush current at startup.  
- **Overcurrent and Thermal Protection:** Enhances reliability.  
- **Low Dropout Operation:** Maintains regulation even when the input voltage is close to the output.  
- **Wide Input Voltage Range:** Suitable for various industrial and automotive applications.  

This information is based on the manufacturer's datasheet for the LM2726M.

Application Scenarios & Design Considerations

High Speed Synchronous MOSFET Driver

Alternative Part Number

  • TPS2828DBVR --: Single-channel high-speed MOSFET gate driver in SOT-23, functionally similar to the LM2726M driver with comparable drive current and supply range.
  • FAN3100C --: Low-side gate driver with similar peak output current and input logic, suitable drop-in functional replacement in many LM2726M applications.
  • ISL8915AFBZ --: Dual high-speed gate driver offering comparable drive strength and timing, usable as an alternative when layout allows a different package.
