Description and Introduction

28V, Low-Power, High-Voltage, Boost or Inverting DC-DC Converter The MAX629ESA-T is a step-up DC-DC converter manufactured by Maxim Integrated (now part of Analog Devices). Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Input Voltage Range:** 0.8V to 28V  
- **Output Voltage Range:** Up to 28V (adjustable)  
- **Output Current:** Up to 200mA (depending on input/output conditions)  
- **Switching Frequency:** 500kHz  
- **Efficiency:** Up to 94%  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 8-pin SOIC (Small Outline Integrated Circuit)  
- **Shutdown Current:** <1µA  

### **Descriptions:**
The MAX629ESA-T is a high-efficiency, low-power, step-up DC-DC converter designed for applications requiring a regulated output voltage higher than the input supply. It is suitable for battery-powered devices, portable electronics, and other low-voltage systems.

### **Features:**
- **Wide Input Voltage Range:** Operates from 0.8V to 28V, making it ideal for single-cell or multi-cell battery applications.  
- **Adjustable Output Voltage:** Allows flexibility for various applications.  
- **High Efficiency:** Up to 94% conversion efficiency.  
- **Low Shutdown Current:** Consumes less than 1µA in shutdown mode, extending battery life.  
- **Internal N-Channel Switch:** Simplifies design by integrating the power switch.  
- **500kHz Switching Frequency:** Enables small external components, reducing PCB space.  
- **Thermal Overload Protection:** Safeguards the device under fault conditions.  

This information is based solely on the manufacturer's datasheet. For detailed application notes, refer to Maxim Integrated's official documentation.
