Description and Introduction

5V/3.3V or Adjustable, 100% Duty Cycle, High-Efficiency, Step-Down DC-DC Controllers The MAX1626 is a step-down switching regulator manufactured by Maxim Integrated (now part of Analog Devices). Below are its key specifications, descriptions, and features:

### **Specifications:**  
- **Input Voltage Range:** 4V to 30V  
- **Output Voltage Range:** Adjustable from 1.25V to 29V  
- **Output Current:** Up to 500mA  
- **Switching Frequency:** 300kHz  
- **Efficiency:** Up to 90%  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package Options:** 8-pin SOIC, 8-pin DIP  

### **Descriptions:**  
The MAX1626 is a high-efficiency, step-down DC-DC converter designed for battery-powered and industrial applications. It integrates a power MOSFET switch, simplifying design while providing stable output voltage regulation.  

### **Features:**  
- **Low Dropout Operation:** Maintains regulation with input voltages close to the output.  
- **Internal Power MOSFET:** Reduces external component count.  
- **Current-Limiting Protection:** Safeguards against overloads.  
- **Low Quiescent Current:** Typically 110µA (shutdown mode: 5µA).  
- **Adjustable Output Voltage:** Set via external resistors.  
- **Thermal Shutdown Protection:** Prevents damage from overheating.  

For detailed application notes, refer to the official datasheet from Analog Devices (formerly Maxim Integrated).
