Description and Introduction

3.3V/5V or Adjustable-Output, Step-Up DC-DC Converters The MAX856CUA 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:**  
- **Input Voltage Range:** 0.7V to 5.5V  
- **Output Voltage Range:** Adjustable from 2V to 5.5V  
- **Output Current:** Up to 300mA (depending on input/output conditions)  
- **Switching Frequency:** 500kHz (typical)  
- **Efficiency:** Up to 90%  
- **Quiescent Current:** 40µA (typical)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 8-pin µMAX (microMAX)  

### **Descriptions:**  
The MAX856CUA is a low-power, step-up DC-DC converter designed for battery-powered applications. It provides a regulated output voltage from a low input voltage, making it suitable for single-cell or dual-cell battery systems. The device integrates a power switch, oscillator, and control logic, requiring minimal external components.  

### **Features:**  
- **Low Start-Up Voltage:** Operates down to 0.7V  
- **Adjustable or Fixed Output Voltage Options**  
- **Internal Power MOSFET Switch**  
- **Low Shutdown Current (<1µA)**  
- **Soft-Start Function to Reduce Inrush Current**  
- **Compact µMAX Package for Space-Constrained Applications**  

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