Description and Introduction

High-Efficiency, Low-Supply-Current, Compact, Step-Up DC-DC Converters The MAX1674EUA+ is a step-up DC-DC converter manufactured by **MAXIM** (now part of Analog Devices). Below are its key specifications, descriptions, and features based on factual data:  

### **Specifications:**  
- **Input Voltage Range:** 0.7V to 5.5V  
- **Output Voltage Range:** Adjustable from 2V to 5.5V  
- **Output Current:** Up to **150mA** (for 3.3V output at 1V input)  
- **Switching Frequency:** **500kHz**  
- **Efficiency:** Up to **94%**  
- **Operating Temperature Range:** **-40°C to +85°C**  
- **Package:** **8-pin μMAX (MSOP)**  

### **Descriptions:**  
- The MAX1674EUA+ is a **low-power, step-up DC-DC converter** optimized for battery-powered applications.  
- It integrates a **high-efficiency, low-noise, PWM boost regulator** with an internal **0.5A N-channel MOSFET switch**.  
- It supports **low start-up voltage (0.7V)**, making it suitable for single-cell or dual-cell battery systems.  
- The device includes **soft-start** to minimize inrush current and **shutdown mode** to reduce power consumption.  

### **Features:**  
- **Ultra-low input voltage operation (down to 0.7V)**  
- **Adjustable or fixed output voltage options**  
- **Low quiescent current (16µA typical)**  
- **Internal MOSFET switch (0.5A peak current)**  
- **Overcurrent and thermal protection**  
- **Small 8-pin μMAX package** for space-constrained designs  

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