Description and Introduction

Chemistry-Independent Battery Chargers The MAX1647EAP+ is a step-down DC-DC converter manufactured by Maxim Integrated (now part of Analog Devices). Below are its key specifications, descriptions, and features:

### **Specifications:**  
- **Input Voltage Range:** 4V to 30V  
- **Output Voltage Range:** Adjustable from 2.5V to 5.5V  
- **Output Current:** Up to 300mA  
- **Switching Frequency:** 500kHz (typical)  
- **Efficiency:** Up to 90%  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 20-pin SSOP (Shrink Small Outline Package)  
- **Regulation Type:** PWM (Pulse-Width Modulation)  

### **Descriptions:**  
The MAX1647EAP+ is a high-efficiency, step-down DC-DC converter designed for low-power applications. It integrates a power MOSFET and control circuitry to provide a regulated output voltage from an input supply ranging from 4V to 30V. The device is optimized for battery-powered systems, portable devices, and industrial applications requiring stable power conversion.

### **Features:**  
- **Low Quiescent Current:** 50µA (typical) in shutdown mode  
- **Internal Power MOSFET:** Reduces external component count  
- **Soft-Start Function:** Prevents inrush current at startup  
- **Undervoltage Lockout (UVLO):** Ensures proper operation under low input voltage  
- **Thermal Shutdown Protection:** Prevents overheating  
- **Adjustable Output Voltage:** Via external resistors  
- **Compact Design:** Suitable for space-constrained applications  

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