Description and Introduction

50mA, Frequency-Selectable, Switched-Capacitor Voltage Converters The MAX860ISA+ is a high-efficiency, step-up DC-DC converter manufactured by **MAXIM** (now part of Analog Devices). Below are its key specifications, descriptions, and features:

### **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  
- **Efficiency:** Up to 95%  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 8-pin SOIC  

### **Descriptions:**  
- The MAX860ISA+ is a **boost (step-up) DC-DC converter** designed for low-voltage applications.  
- It integrates a **power MOSFET** to minimize external component count.  
- Suitable for battery-powered devices, portable electronics, and energy-harvesting applications.  

### **Features:**  
- **Low Start-up Voltage:** Operates down to **0.7V** input.  
- **Adjustable Output Voltage:** Set via external resistors.  
- **Low Quiescent Current:** 30µA (typical) for improved efficiency.  
- **Internal Soft-Start:** Reduces inrush current.  
- **Automatic Pulse-Frequency Modulation (PFM):** Enhances efficiency at light loads.  
- **Overcurrent and Thermal Protection:** Safeguards the device under fault conditions.  

This information is sourced from the **MAXIM datasheet** for the MAX860ISA+.
