Description and Introduction

3.3V/5V or Adjustable-Output / Step-Up DC-DC Converters The MAX859CSA is a step-up DC-DC converter manufactured by Maxim Integrated (now part of Analog Devices). Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Input Voltage Range:** 0.7V to 5.5V  
- **Output Voltage:** Adjustable from 2V to 5.5V  
- **Output Current:** Up to 300mA (depending on input/output conditions)  
- **Switching Frequency:** 500kHz  
- **Efficiency:** Up to 94%  
- **Operating Temperature Range:** 0°C to +70°C  
- **Package:** 8-pin SOIC  

### **Descriptions:**
The MAX859CSA is a low-power, step-up DC-DC converter designed for battery-powered applications. It integrates a power switch and provides a regulated output voltage from a low input supply, making it suitable for portable devices.  

### **Features:**
- **Low Start-Up Voltage:** Operates down to 0.7V  
- **Internal Power Switch:** Simplifies design  
- **Adjustable Output Voltage:** Set via external resistors  
- **Low Quiescent Current:** 19µA (typical)  
- **Soft-Start Function:** Reduces inrush current  
- **Overcurrent Protection:** Enhances reliability  
- **Small Footprint:** 8-pin SOIC package
