Description and Introduction

2MHz, 600mA Step-Down DC-DC Converter in SOT 23-5 5-SOT-23 -30 to 85 The LM3674MF-ADJ/NOPB is a step-down DC-DC converter manufactured by National Semiconductor (NSC). Below are its specifications, descriptions, and features based on factual information from Ic-phoenix technical data files:

### **Specifications:**
- **Input Voltage Range:** 2.7V to 5.5V  
- **Output Voltage Range:** Adjustable from 0.8V to VIN  
- **Output Current:** Up to 600mA  
- **Switching Frequency:** 2MHz (typical)  
- **Efficiency:** Up to 96%  
- **Quiescent Current:** 16µA (typical)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** SOT-23-5  

### **Descriptions:**
- The LM3674MF-ADJ/NOPB is a high-efficiency, step-down DC-DC converter optimized for battery-powered applications.  
- It provides a regulated adjustable output voltage with minimal external components.  
- The device operates in pulse-width modulation (PWM) mode at higher loads and automatically switches to power-saving pulse frequency modulation (PFM) mode at light loads for improved efficiency.  

### **Features:**
- **Adjustable Output Voltage** (via external resistors)  
- **High Efficiency** (up to 96%)  
- **Low Quiescent Current** (16µA typical)  
- **2MHz Switching Frequency** (allows for small external components)  
- **Internal Soft-Start** (reduces inrush current)  
- **Thermal Shutdown Protection**  
- **Overcurrent Protection**  
- **Available in a Small SOT-23-5 Package**  

This information is strictly based on the manufacturer's datasheet and technical documentation.
