Description and Introduction

High Speed Synchronous/Asynchronous MOSFET Driver The LM2722MX is a high-efficiency, synchronous step-down DC-DC converter manufactured by National Semiconductor (NSC).  

### **Specifications:**  
- **Input Voltage Range:** 2.9V to 14V  
- **Output Voltage Range:** 0.8V to 5V (adjustable via external resistors)  
- **Output Current:** Up to 3A  
- **Switching Frequency:** 300kHz  
- **Efficiency:** Up to 95%  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** SOIC-8 (Surface Mount)  

### **Descriptions:**  
The LM2722MX is a synchronous buck regulator designed for high-efficiency power conversion. It integrates both high-side and low-side MOSFETs, reducing external component count. It is suitable for applications requiring precise voltage regulation with high current output.  

### **Features:**  
- Integrated power MOSFETs  
- Adjustable output voltage  
- Overcurrent and thermal protection  
- Soft-start function to limit inrush current  
- Low shutdown current (<1µA)  
- Synchronous rectification for improved efficiency  

This information is based on the manufacturer's datasheet.

Application Scenarios & Design Considerations

High Speed Synchronous/Asynchronous MOSFET Driver

Alternative Part Number

  • TPS51116PWP --: DDR memory power controller with similar function and pin-compatible design philosophy; TI is the direct successor to National Semiconductor's power management line.
  • ISL6537CRZ --: Integrated DDR power supply controller offering comparable multi-rail regulation for memory termination, widely used as a drop-in functional replacement.
  • MAX8632ETI+ --: Dual-output DDR power controller with similar voltage regulation and sequencing features, suitable as a functional alternative.
