Description and Introduction

3A, 1MHz, DDR Memory Termination Supply The MAX1809EEE-T is a high-efficiency, step-up 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:**
- **Manufacturer:** Maxim Integrated  
- **Part Number:** MAX1809EEE-T  
- **Package:** 16-QSOP (Exposed Pad)  
- **Input Voltage Range:** 0.7V to 5.5V  
- **Output Voltage Range:** Adjustable from 1.8V to 5.5V  
- **Output Current:** Up to 300mA (depending on input/output conditions)  
- **Switching Frequency:** 1MHz (typical)  
- **Efficiency:** Up to 95%  
- **Operating Temperature Range:** -40°C to +85°C  
- **Shutdown Current:** <1µA  

### **Descriptions:**
The MAX1809EEE-T is a synchronous step-up DC-DC converter optimized for low-input-voltage applications. It integrates a high-efficiency boost regulator with an internal synchronous rectifier, eliminating the need for an external Schottky diode. The device is designed for battery-powered portable devices, energy harvesting, and other low-power applications requiring high efficiency in a compact footprint.

### **Features:**
- **Ultra-Low Input Voltage Operation:** Starts up from inputs as low as 0.7V.  
- **Internal Synchronous Rectifier:** Improves efficiency and eliminates external diode.  
- **Adjustable Output Voltage:** Configurable via external resistors.  
- **Low Quiescent Current:** 30µA (typical) for improved battery life.  
- **Soft-Start Function:** Prevents inrush current at startup.  
- **Thermal Shutdown Protection:** Safeguards against overheating.  
- **Small Footprint:** 16-QSOP package with exposed pad for thermal dissipation.  

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