Description and Introduction

xDSL/Cable Modem Triple/Quintuple Output Power Supplies The MAX1864TEEE+T is a step-down DC-DC converter manufactured by Maxim Integrated (now part of Analog Devices). Below are its specifications, descriptions, and features based on factual information:

### **Specifications:**  
- **Input Voltage Range:** 2.5V to 5.5V  
- **Output Voltage Range:** Adjustable from 0.8V to VIN  
- **Output Current:** Up to 600mA  
- **Switching Frequency:** 1MHz (typical)  
- **Efficiency:** Up to 95%  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 16-pin TQFN (3mm x 3mm)  
- **Topology:** Synchronous Buck Converter  
- **Dropout Voltage:** 100mV (typical at 300mA load)  
- **Quiescent Current:** 30µA (typical)  

### **Descriptions:**  
The MAX1864TEEE+T is a high-efficiency, step-down DC-DC converter designed for low-power applications. It integrates synchronous rectification to minimize external components and improve efficiency. The device operates at a fixed 1MHz switching frequency, allowing the use of small inductors and capacitors.  

### **Features:**  
- **Low Quiescent Current:** 30µA (typical) extends battery life.  
- **Pulse-Width Modulation (PWM) Mode:** Ensures stable operation under load.  
- **100% Duty Cycle Operation:** Supports low dropout for extended battery runtime.  
- **Internal Soft-Start:** Reduces inrush current.  
- **Short-Circuit Protection:** Enhances reliability.  
- **Thermal Shutdown:** Prevents overheating.  
- **Adjustable Output Voltage:** Set via external resistors.
