Description and Introduction

Advanced-Chemistry-Independent, Level-2 Battery Chargers with Input Current Limiting The MAX1645A is a step-up DC-DC converter manufactured by Maxim Integrated (now part of Analog Devices). Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:

### **Specifications:**  
- **Input Voltage Range:** 1.2V to 16.5V  
- **Output Voltage:** Adjustable from 2V to 16.5V  
- **Output Current:** Up to 300mA (depending on input/output conditions)  
- **Switching Frequency:** 500kHz  
- **Efficiency:** Up to 90%  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 8-pin SOIC  

### **Description:**  
The MAX1645A is a high-efficiency, low-power, step-up DC-DC converter designed for battery-powered applications. It integrates a power MOSFET and provides a regulated output voltage from a single-cell or multi-cell battery input. The device is optimized for low-voltage operation and is suitable for portable electronics, handheld devices, and other power-sensitive applications.  

### **Features:**  
- **Low Start-Up Voltage:** Operates down to 1.2V  
- **Adjustable Output Voltage:** Set via external resistors  
- **Internal Power MOSFET:** Simplifies design and reduces external components  
- **Low Quiescent Current:** Typically 50µA (shutdown mode: <1µA)  
- **Pulse-Width Modulation (PWM) Control:** Ensures stable operation  
- **Overcurrent Protection:** Safeguards against excessive load conditions  
- **Small Footprint:** 8-pin SOIC package for space-constrained applications  

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