Description and Introduction

Regulated 90mA Buck-Boost Switched Capacitor DC/DC Converter The LM3354MMX-1.8 is a step-down DC-DC converter manufactured by National Semiconductor (NS). Below are its key specifications, descriptions, and features:  

### **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:** 17µA (typical)  

### **Descriptions:**  
- The LM3354MMX-1.8 is a high-efficiency, step-down (buck) DC-DC converter optimized for battery-powered applications.  
- It integrates a synchronous rectifier for improved efficiency and requires minimal external components.  
- The fixed 1.8V output makes it suitable for low-voltage digital circuits.  

### **Features:**  
- **Synchronous Rectification:** Enhances efficiency and reduces power loss.  
- **Low Quiescent Current:** Ideal for battery-operated devices.  
- **PWM/PFM Auto Mode:** Optimizes efficiency across load conditions.  
- **Internal Soft-Start:** Prevents inrush current at startup.  
- **Thermal Shutdown & Overcurrent Protection:** Ensures safe operation.  
- **Small Footprint:** Suitable for space-constrained designs.
