Description and Introduction

CDMA Cellular/PCS System Power Supplies The MAX1799AEUP is a step-up DC-DC converter manufactured by Maxim Integrated (now part of Analog Devices). Below are its key specifications, descriptions, and features based on factual information:

### **Specifications:**
- **Input Voltage Range:** 0.7V to 5.5V  
- **Output Voltage Range:** Adjustable from 2.5V to 5.5V (via external resistors)  
- **Output Current:** Up to 300mA (depending on input/output conditions)  
- **Switching Frequency:** 500kHz (typical)  
- **Efficiency:** Up to 90%  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 20-pin TSSOP (Thin Shrink Small Outline Package)  

### **Descriptions:**
- The MAX1799AEUP is a high-efficiency, step-up DC-DC converter optimized for low-input-voltage applications.  
- It integrates a synchronous rectifier to improve efficiency and reduce external component count.  
- Suitable for battery-powered devices, portable electronics, and energy-harvesting applications.  

### **Features:**
- **Low Start-Up Voltage:** Operates down to 0.7V input.  
- **Synchronous Rectification:** Enhances efficiency and eliminates the need for an external Schottky diode.  
- **Adjustable Output Voltage:** Set via external resistors.  
- **Soft-Start Function:** Prevents inrush current at startup.  
- **Low Quiescent Current:** Typically 30µA (improves battery life).  
- **Thermal Shutdown & Overcurrent Protection:** Enhances device reliability.  
- **Small Footprint:** 20-pin TSSOP package saves board space.
