Description and Introduction

xDSL/Cable Modem Triple/Quintuple Output Power Supplies The MAX1864TEEE is a DC-DC converter manufactured by Maxim Integrated (now part of Analog Devices). Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:

### **Specifications:**
- **Manufacturer:** Maxim Integrated (now Analog Devices)  
- **Part Number:** MAX1864TEEE  
- **Package:** 16-QSOP (Exposed Pad)  
- **Type:** Step-Up (Boost) DC-DC Converter  
- **Input Voltage Range:** 0.7V to 5.5V  
- **Output Voltage Range:** Adjustable (up to 5.5V)  
- **Output Current:** Up to 300mA (depending on input/output conditions)  
- **Switching Frequency:** 1.2MHz (typical)  
- **Efficiency:** Up to 95%  
- **Operating Temperature Range:** -40°C to +85°C  

### **Descriptions:**
The MAX1864TEEE is a high-efficiency, step-up DC-DC converter designed for low-voltage applications. It integrates a synchronous rectifier to improve efficiency and reduce external component count. The device is optimized for battery-powered systems, providing stable output voltage from very low input voltages.

### **Features:**
- **Low Start-Up Voltage:** Operates down to 0.7V input  
- **Synchronous Rectification:** Improves efficiency  
- **Adjustable Output Voltage:** Set via external resistors  
- **1.2MHz Fixed Switching Frequency:** Reduces external component size  
- **Low Quiescent Current:** 20µA (typical) in shutdown mode  
- **Internal Soft-Start:** Reduces inrush current  
- **Thermal Shutdown Protection:** Prevents overheating  
- **Undervoltage Lockout (UVLO):** Ensures proper operation  

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