Description and Introduction

Power Source Selector for Dual-Battery Systems The **MAX1773AEUP+** is a high-efficiency, 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:

### **Manufacturer:**  
- **MAXIM INTEGRATED** (now part of Analog Devices)  

### **Specifications:**  
- **Input Voltage Range:** 0.7V to 5.5V  
- **Output Voltage Range:** Adjustable from 2V to 5.5V  
- **Output Current:** Up to 1A (depending on input/output conditions)  
- **Switching Frequency:** 500kHz (fixed)  
- **Efficiency:** Up to 96%  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 20-TSSOP (Exposed Pad)  

### **Descriptions:**  
- The MAX1773AEUP+ is a **boost (step-up) DC-DC converter** designed for low-input-voltage applications.  
- It integrates a **high-efficiency synchronous rectifier**, reducing the need for external diodes.  
- Suitable for battery-powered devices, portable electronics, and energy-harvesting applications.  

### **Features:**
