Description and Introduction

Advanced Chemistry-Independent, Level 2 Battery Charger with Input Current Limiting The MAX1645BEEI-T 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 1.25V to 16V  
- **Output Current:** Up to 1A  
- **Switching Frequency:** 300kHz  
- **Efficiency:** Up to 90%  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 16-pin QSOP (QSOP-16)  

### **Descriptions:**
The MAX1645BEEI-T is a high-efficiency, step-down DC-DC converter designed for applications requiring a regulated output voltage from a higher input voltage. It features an internal N-channel MOSFET switch for high efficiency and low power dissipation. The device is suitable for battery-powered systems, industrial controls, and automotive applications.

### **Features:**
- **Wide Input Voltage Range (4V to 30V)**  
- **Adjustable Output Voltage (1.25V to 16V)**  
- **Internal N-Channel MOSFET Switch**  
- **Low Dropout Operation**  
- **Current-Mode PWM Control**  
- **Undervoltage Lockout (UVLO) Protection**  
- **Thermal Shutdown Protection**  
- **Soft-Start Functionality**  
- **Low Quiescent Current (200µA typical)**  

This device is designed for compact, high-efficiency power conversion in space-constrained applications.
