Description and Introduction

Regulated 90mA Buck-Boost Switched Capacitor DC/DC Converter The LM3354MM-1.8 is a step-down DC-DC converter manufactured by National Semiconductor (NS). Below are the factual details from Ic-phoenix technical data files:

### **Specifications:**  
- **Output Voltage:** 1.8V (fixed)  
- **Input Voltage Range:** 2.7V to 5.5V  
- **Output Current:** Up to 600mA  
- **Switching Frequency:** 1.6MHz (typical)  
- **Efficiency:** Up to 95%  
- **Package:** 8-pin VSSOP (MSOP)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Quiescent Current:** 30µA (typical)  

### **Descriptions:**  
The LM3354MM-1.8 is a high-efficiency, step-down (buck) DC-DC converter designed for low-power applications. It integrates a synchronous rectifier to improve efficiency and reduce external component count. The fixed 1.8V output makes it suitable for powering low-voltage digital circuits, portable devices, and battery-powered systems.  

### **Features:**  
- **Fixed 1.8V Output**  
- **Synchronous Rectification** for high efficiency  
- **Low Quiescent Current** for improved battery life  
- **Internal Soft-Start** to limit inrush current  
- **Over-Temperature Protection**  
- **Short-Circuit Protection**  
- **Small Footprint** (VSSOP-8 package)  

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