Description and Introduction

3.3V/5V or Adjustable-Output / Single-Cell DC-DC Converters The MAX866EUA+ is a step-up DC-DC converter manufactured by Maxim Integrated (now part of Analog Devices). Below are its specifications, descriptions, and features based on factual data:

### **Specifications:**
- **Manufacturer:** Maxim Integrated  
- **Part Number:** MAX866EUA+  
- **Package:** 8-pin μMAX (MSOP)  
- **Input Voltage Range:** 0.7V to 5.5V  
- **Output Voltage Range:** Adjustable (up to 5.5V)  
- **Output Current:** Up to 300mA (depending on input/output conditions)  
- **Switching Frequency:** 500kHz (fixed)  
- **Efficiency:** Up to 90%  
- **Operating Temperature Range:** -40°C to +85°C  
- **Shutdown Current:** <1μA  

### **Descriptions:**
The MAX866EUA+ is a high-efficiency, step-up DC-DC converter designed for low-voltage applications. It integrates a power switch and can generate a regulated output voltage from input voltages as low as 0.7V. It is commonly used in battery-powered devices, portable electronics, and other applications requiring a stable voltage supply from a low input source.

### **Features:**
- **Low Start-Up Voltage:** Operates from inputs as low as 0.7V.  
- **Adjustable Output Voltage:** Set via external resistors.  
- **Internal Power Switch:** Eliminates the need for an external MOSFET.  
- **Low Quiescent Current:** Typically 30μA for improved efficiency.  
- **Automatic Pulse-Frequency Modulation (PFM):** Enhances efficiency at light loads.  
- **Short-Circuit Protection:** Prevents damage during fault conditions.  
- **Thermal Shutdown:** Protects the device from overheating.  

This information is strictly based on the manufacturer's datasheet.
