Description and Introduction

Dual Synchronous Step-Down DC-DC Converter with Dynamic Voltage Scaling Function The LM3370SD-3806 is a step-down DC-DC converter manufactured by National Semiconductor (NS).  

### **Specifications:**  
- **Input Voltage Range:** 2.7V to 5.5V  
- **Output Voltage:** 3.8V (fixed)  
- **Output Current:** Up to 600mA  
- **Switching Frequency:** 2.25MHz (typical)  
- **Efficiency:** Up to 95%  
- **Package:** 10-pin LLP (3mm x 3mm)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Shutdown Current:** <1µA  

### **Descriptions and Features:**  
- **Step-Down DC-DC Converter:** Converts a higher input voltage to a regulated lower output voltage.  
- **Fixed Output Voltage:** Pre-set to 3.8V.  
- **High Efficiency:** Uses synchronous rectification for improved power conversion.  
- **Low Dropout Operation:** Maintains regulation even when input voltage is close to output.  
- **Internal Soft-Start:** Reduces inrush current during startup.  
- **Thermal Shutdown Protection:** Prevents damage from overheating.  
- **Short-Circuit Protection:** Safeguards against output faults.  
- **Small Footprint:** Suitable for space-constrained applications.  

This device is commonly used in portable electronics, battery-powered systems, and embedded applications requiring efficient power conversion.
