Description and Introduction

LM3671, LM3671Q 2MHz, 600mA Step-Down DC-DC Converter The LM3671MF-2.5 is a step-down DC-DC converter manufactured by Texas Instruments (formerly National Semiconductor, NS).  

### **Specifications:**  
- **Output Voltage:** Fixed 2.5V  
- **Input Voltage Range:** 2.7V to 5.5V  
- **Output Current:** Up to 600mA  
- **Switching Frequency:** 2MHz (typical)  
- **Efficiency:** Up to 96%  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** SOT-23-5  
- **Regulation Type:** PWM/PFM (Automatic Mode Switching)  
- **Quiescent Current:** 16µA (typical) in PFM mode  

### **Descriptions:**  
The LM3671MF-2.5 is a high-efficiency, step-down DC-DC converter optimized for battery-powered applications. It provides a fixed 2.5V output and supports a wide input voltage range, making it suitable for portable electronics. The device operates in either PWM (for high load conditions) or PFM (for light load efficiency) mode automatically.  

### **Features:**  
- **High Efficiency:** Up to 96%  
- **Low Quiescent Current:** Extends battery life  
- **Internal Synchronous Rectification:** Improves efficiency  
- **Thermal Shutdown & Current Limiting:** Protection features  
- **Small Footprint:** SOT-23-5 package for space-constrained designs  
- **Fast Transient Response:** Suitable for dynamic loads
