Description and Introduction

Chemistry-Independent Battery Chargers The MAX1647EAP 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 data:

### **Specifications:**  
- **Input Voltage Range:** 1.2V to 16.5V  
- **Output Voltage Range:** Adjustable from 2V to 16.5V  
- **Output Current:** Up to 300mA (depending on input/output conditions)  
- **Switching Frequency:** 500kHz (fixed)  
- **Efficiency:** Up to 90%  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 20-pin SSOP (Shrink Small Outline Package)  

### **Descriptions:**  
- The MAX1647EAP is a high-efficiency, step-up DC-DC converter designed for low-input-voltage applications.  
- It integrates a power MOSFET switch, reducing external component count.  
- Suitable for battery-powered systems, portable devices, and other applications requiring a regulated higher voltage from a low-voltage source.  

### **Features:**  
- **Low Start-Up Voltage:** Operates down to 1.2V input.  
- **Adjustable Output Voltage:** Set via external resistors.  
- **Internal Power MOSFET:** Simplifies design and reduces external parts.  
- **Low Quiescent Current:** 50µA (typical) in shutdown mode.  
- **Overcurrent Protection:** Prevents damage under fault conditions.  
- **Thermal Shutdown:** Protects the IC from overheating.  

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