Description and Introduction

50mA, Frequency-Selectable, Switched-Capacitor Voltage Converters The MAX860IUA+ is a product from Maxim Integrated (now part of Analog Devices). Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:

### **Manufacturer:**  
Maxim Integrated (Analog Devices)  

### **Part Number:**  
MAX860IUA+  

### **Description:**  
The MAX860IUA+ is a low-power, step-up DC-DC converter designed for applications requiring a regulated output voltage higher than the input voltage. It is commonly used in battery-powered devices, portable electronics, and other low-power systems.  

### **Key Features:**  
- **Input Voltage Range:** 0.7V to 5.5V  
- **Output Voltage:** Adjustable (up to 5.5V)  
- **Output Current:** Up to 300mA (depending on input/output conditions)  
- **Efficiency:** Up to 90%  
- **Switching Frequency:** 500kHz  
- **Low Quiescent Current:** 15µA (typical)  
- **Shutdown Current:** <1µA  
- **Package:** 8-pin µMAX (Ultra-small outline package)  
- **Operating Temperature Range:** -40°C to +85°C  

### **Applications:**  
- Battery-powered devices  
- Portable electronics  
- LED drivers  
- Energy harvesting systems  

### **Additional Notes:**  
- The MAX860IUA+ includes internal power MOSFETs, reducing external component count.  
- It features a soft-start function to limit inrush current.  
- The device is designed for space-constrained applications due to its small footprint.  

This information is based on the manufacturer's datasheet and technical documentation. For detailed electrical characteristics and application circuits, refer to the official datasheet.
