Description and Introduction

3.3V/5V or Adjustable-Output / Single-Cell DC-DC Converters The MAX867ESA is a DC-DC converter manufactured by Maxim Integrated. Below are its specifications, descriptions, and features based on factual information from Ic-phoenix technical data files:

### **Specifications:**
- **Manufacturer:** Maxim Integrated  
- **Part Number:** MAX867ESA  
- **Type:** Step-Up (Boost) DC-DC Converter  
- **Input Voltage Range:** 0.7V to 5.5V  
- **Output Voltage Range:** Adjustable (up to 5.5V)  
- **Output Current:** Up to 300mA (depending on input voltage)  
- **Switching Frequency:** 500kHz  
- **Efficiency:** Up to 90%  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 8-pin SOIC  

### **Descriptions:**
The MAX867ESA is a high-efficiency, step-up DC-DC converter designed for low-input-voltage applications. It is optimized for battery-powered systems, providing a regulated output voltage from a single-cell or dual-cell battery input. The device integrates a power switch, minimizing external component count.

### **Features:**
- **Low Start-Up Voltage:** Operates down to 0.7V input.  
- **Adjustable Output Voltage:** Configurable via external resistors.  
- **Internal Power Switch:** Reduces external component requirements.  
- **Low Quiescent Current:** 30µA (typical) for improved battery life.  
- **Automatic Pulse-Frequency Modulation (PFM):** Enhances efficiency at light loads.  
- **Short-Circuit Protection:** Improves reliability.  
- **Small Footprint:** 8-pin SOIC package for space-constrained applications.  

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