Description and Introduction

High-Frequency / High-Power / Low-Noise / Step-Up DC-DC Converter The MAX1708EEE is a step-up DC-DC converter manufactured by Maxim Integrated (now part of Analog Devices). Below are its key specifications, descriptions, and features:

### **Specifications:**  
- **Input Voltage Range:** 0.7V to 5.5V  
- **Output Voltage Range:** Adjustable from 2V to 5.5V  
- **Output Current:** Up to 300mA (depending on input/output conditions)  
- **Switching Frequency:** 500kHz (typical)  
- **Efficiency:** Up to 95%  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 16-QSOP (Quad Flat Small Outline Package)  

### **Description:**  
The MAX1708EEE is a high-efficiency, low-voltage, step-up DC-DC converter designed for battery-powered applications. It integrates a synchronous rectifier to improve efficiency and reduce external component count. The device is optimized for single-cell or dual-cell alkaline/NiMH battery inputs and can generate stable output voltages for portable electronics.  

### **Features:**  
- **True Low-Voltage Operation:** Starts up with inputs as low as 0.7V.  
- **Synchronous Rectification:** Improves efficiency and eliminates the need for an external Schottky diode.  
- **Adjustable Output Voltage:** Set via an external resistor divider.  
- **Low Quiescent Current:** 16µA (typical) in shutdown mode, extending battery life.  
- **Internal Soft-Start:** Reduces inrush current during startup.  
- **Overcurrent Protection:** Safeguards the device and load.  
- **Small Footprint:** 16-QSOP package saves board space.  

The MAX1708EEE is commonly used in portable devices, such as digital cameras, PDAs, and wireless peripherals, where efficient power conversion from low-voltage batteries is required.
