Description and Introduction

Switched Capacitor Voltage Converter The LM3351MM is a power management IC manufactured by National Semiconductor (NS). Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:

### **Specifications:**
- **Manufacturer:** National Semiconductor (NS)  
- **Part Number:** LM3351MM  
- **Package:** 8-Pin VSSOP (MSOP)  
- **Input Voltage Range:** 2.7V to 5.5V  
- **Output Voltage Range:** Adjustable (via external resistors)  
- **Output Current:** Up to 300mA  
- **Switching Frequency:** 1.6MHz (typical)  
- **Efficiency:** Up to 95%  
- **Operating Temperature Range:** -40°C to +85°C

### **Descriptions:**
The LM3351MM is a high-efficiency, step-down (buck) DC-DC converter designed for low-power applications. It integrates a synchronous rectifier to minimize external components and improve efficiency. The device is optimized for battery-powered systems, portable electronics, and other space-constrained applications.

### **Features:**
- **Synchronous Buck Regulator:** Reduces power loss and improves efficiency.  
- **Low Quiescent Current:** Enhances battery life in portable applications.  
- **Adjustable Output Voltage:** Configurable via external resistors.  
- **Internal Soft-Start:** Prevents inrush current during startup.  
- **Overcurrent Protection:** Safeguards the device and load.  
- **Thermal Shutdown:** Protects against overheating.  
- **Small Footprint:** 8-pin VSSOP package for space-saving designs.  

This information is based on the manufacturer's datasheet and technical documentation.
