Description and Introduction

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

### **Specifications:**
- **Manufacturer:** Maxim Integrated (now Analog Devices)  
- **Part Number:** MAX867ESA+  
- **Package:** 8-pin SOIC (Small Outline Integrated Circuit)  
- **Input Voltage Range:** 1.8V to 5.5V  
- **Output Voltage Options:** Fixed (3.3V or 5V) or Adjustable  
- **Output Current:** Up to 50mA  
- **Switching Frequency:** 500kHz (typical)  
- **Efficiency:** Up to 90%  
- **Operating Temperature Range:** -40°C to +85°C  

### **Descriptions:**
The MAX867ESA+ is a low-noise, regulated charge pump DC-DC converter designed for small, portable applications. It provides a regulated output voltage from an input supply as low as 1.8V, making it suitable for battery-powered devices. The device uses a charge pump architecture, eliminating the need for an inductor, which reduces board space and cost.  

### **Features:**
- **Low-Noise Operation:** Minimizes interference in sensitive applications.  
- **No Inductor Required:** Simplifies PCB design and reduces component count.  
- **Low Quiescent Current:** Typically 50µA, improving battery life.  
- **Soft-Start Function:** Prevents inrush current at startup.  
- **Short-Circuit Protection:** Enhances reliability.  
- **Small Footprint:** 8-pin SOIC package for space-constrained designs.  
- **Adjustable or Fixed Output:** Supports 3.3V, 5V, or user-defined output.  

This information is based solely on the manufacturer's datasheet and specifications.
