Description and Introduction

Regulated 90mA Buck-Boost Switched Capacitor DC/DC Converter The LM3354MM-4.1 is a step-down DC-DC converter manufactured by National Semiconductor (NS).  

### **Specifications:**  
- **Input Voltage Range:** 2.7V to 5.5V  
- **Output Voltage:** Fixed 4.1V  
- **Output Current:** Up to 400mA  
- **Switching Frequency:** 1.6MHz (typical)  
- **Efficiency:** Up to 96%  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 8-pin VSSOP (MM)  

### **Descriptions:**
