Description and Introduction

3.3V/5V or Adjustable Output, Step-Up DC-DC Converters The MAX856CUA-T is a step-up DC-DC converter manufactured by Maxim Integrated. Below are its key specifications, descriptions, and features:

### **Specifications:**  
- **Input Voltage Range:** 0.7V to 5.5V  
- **Output Voltage:** Adjustable from 2.7V to 5.5V (factory preset options available)  
- **Output Current:** Up to 300mA (depending on input voltage)  
- **Switching Frequency:** 500kHz  
- **Efficiency:** Up to 90%  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 8-pin µMAX (UCSP also available)  
- **Shutdown Current:** <1µA  

### **Descriptions:**  
The MAX856CUA-T is a low-power, step-up DC-DC converter designed for battery-powered applications. It integrates a power switch, rectifier, and control circuitry, requiring minimal external components. It is optimized for low-input-voltage operation, making it suitable for single-cell or dual-cell battery systems.  

### **Features:**  
- **Low Start-Up Voltage:** Operates down to 0.7V  
- **Adjustable or Fixed Output Voltage**  
- **Internal Power Switch and Rectifier**  
- **Low Quiescent Current (40µA typical)**  
- **Compact µMAX Package**  
- **Overcurrent Protection**  
- **Thermal Shutdown Protection**  

This device is commonly used in portable electronics, medical devices, and other battery-powered systems requiring efficient voltage conversion.
