Description and Introduction

Tracking / Sinking and Sourcing / Synchronous Buck Controller for DDR Memory and Termination Supplies The MAX1917EEE is a high-efficiency, step-down DC-DC converter manufactured by Maxim Integrated. Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:

### **Specifications:**  
- **Input Voltage Range:** 4.5V to 28V  
- **Output Voltage Range:** Adjustable from 1.25V to 5.5V  
- **Output Current:** Up to 2A  
- **Switching Frequency:** 300kHz  
- **Efficiency:** Up to 95%  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 16-QSOP  

### **Descriptions:**  
The MAX1917EEE is a synchronous step-down DC-DC converter designed for high-efficiency power conversion in applications requiring a regulated output voltage. It integrates both high-side and low-side MOSFETs, reducing external component count and board space.  

### **Features:**  
- **Synchronous Rectification:** Improves efficiency by eliminating diode losses.  
- **Adjustable Output Voltage:** Set via external resistors.  
- **Low Dropout Operation:** Allows operation with input voltages close to the output.  
- **Internal Soft-Start:** Reduces inrush current during startup.  
- **Overcurrent & Thermal Protection:** Safeguards the device under fault conditions.  
- **Low Quiescent Current:** Enhances efficiency at light loads.  

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