Description and Introduction

High-Efficiency / Low-Supply-Current / Compact / Step-Up DC-DC Converters The MAX1676EUB is a step-up DC-DC converter manufactured by Maxim Integrated (now part of Analog Devices). Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:

### **Specifications:**  
- **Manufacturer:** Maxim Integrated  
- **Part Number:** MAX1676EUB  
- **Package:** 10-pin µMAX (MicroMAX)  
- **Input Voltage Range:** 0.7V to 5.5V  
- **Output Voltage Range:** Adjustable from 2V to 5.5V (fixed 3.3V or 5V options available)  
- **Output Current:** Up to 200mA (for 3.3V output)  
- **Switching Frequency:** 500kHz  
- **Efficiency:** Up to 94%  
- **Operating Temperature Range:** -40°C to +85°C  

### **Descriptions:**  
The MAX1676EUB is a high-efficiency, step-up DC-DC converter designed for low-input-voltage applications. It is optimized for battery-powered systems, providing regulated output voltages from very low input voltages (as low as 0.7V). The device integrates a power switch, oscillator, and control circuitry in a compact µMAX package.  

### **Features:**  
- **Low Start-Up Voltage:** Operates down to 0.7V.  
- **Adjustable or Fixed Output Voltage:** Supports 3.3V or 5V fixed outputs or adjustable via external resistors.  
- **High Efficiency:** Up to 94% efficiency with synchronous rectification.  
- **Low Quiescent Current:** Typically 16µA in shutdown mode.  
- **Internal Power MOSFET:** Eliminates the need for an external switch.  
- **Overcurrent Protection:** Built-in to safeguard the circuit.  
- **Small Footprint:** 10-pin µMAX package for space-constrained applications.  

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

Application Scenarios & Design Considerations
