Description and Introduction

Dual / High-Efficiency / PFM / Step-Up DC-DC Controller The MAX863EEE is a DC-DC converter manufactured by Maxim Integrated. Below are the factual details from Ic-phoenix technical data files:

### **Manufacturer:**  
Maxim Integrated  

### **Specifications:**  
- **Input Voltage Range:** 2.5V to 5.5V  
- **Output Voltage Range:** Adjustable (via external resistors)  
- **Output Current:** Up to 500mA  
- **Switching Frequency:** 300kHz  
- **Efficiency:** Up to 95%  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 16-QSOP  

### **Descriptions:**  
The MAX863EEE is a step-up (boost) DC-DC converter designed for low-power applications. It provides a regulated output voltage from a low input voltage source, making it suitable for battery-powered devices.  

### **Features:**  
- Low quiescent current (typically 50µA)  
- Internal power MOSFET switch  
- Soft-start function to reduce inrush current  
- Overcurrent protection  
- Small footprint due to QSOP package
