Description and Introduction

2MHz , 600mA Step-Down DC-DC Converter in SOT23-5 The LM3671MF-1.5 is a step-down DC-DC converter manufactured by Texas Instruments (NS stands for National Semiconductor, which was acquired by TI).  

### **Specifications:**  
- **Output Voltage:** 1.5V (fixed)  
- **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  

### **Descriptions:**  
- The LM3671MF-1.5 is a high-efficiency, step-down (buck) DC-DC converter optimized for battery-powered applications.  
- It provides a fixed 1.5V output with a low quiescent current, making it suitable for portable devices.  
- The device uses pulse-width modulation (PWM) for high efficiency across varying load conditions.  

### **Features:**  
- **Low Quiescent Current:** 16µA (typical) in power-save mode  
- **Synchronizable Switching Frequency:** Allows noise-sensitive applications to avoid interference  
- **Internal Soft-Start:** Reduces inrush current  
- **Thermal Shutdown & Overcurrent Protection:** Enhances reliability  
- **Small Form Factor:** SOT-23-5 package for space-constrained designs  

This information is based solely on the datasheet and manufacturer-provided details.
