Description and Introduction

2A, Low-Voltage, Step-Down Regulator with Synchronous Rectification and Internal Switches The MAX1644 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:**
- **Input Voltage Range:** 2.5V to 16.5V  
- **Output Voltage Range:** Adjustable from 1.25V to 16V  
- **Output Current:** Up to 1A  
- **Switching Frequency:** 300kHz  
- **Efficiency:** Up to 96%  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package Type:** 8-pin SOIC, 8-pin DIP  

### **Descriptions:**
The MAX1644 is a high-efficiency, step-down DC-DC converter designed for battery-powered and low-power applications. It integrates a power MOSFET switch and provides a regulated output voltage with minimal external components. The device is optimized for high efficiency and low quiescent current, making it suitable for portable and battery-operated systems.

### **Features:**
- **High Efficiency:** Up to 96% efficiency reduces power loss.  
- **Low Quiescent Current:** Typically 110µA, extending battery life.  
- **Adjustable Output Voltage:** Set via external resistors.  
- **Internal Power MOSFET:** Simplifies design and reduces external component count.  
- **Soft-Start Function:** Prevents inrush current at startup.  
- **Overcurrent Protection:** Safeguards the device and load.  
- **Thermal Shutdown:** Protects against overheating.  

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