Description and Introduction

Step-Up/Down DC-DC Converter in QSOP Package The MAX1672EEE+ is a step-up DC-DC converter manufactured by **MAXIM** (now part of Analog Devices).  

### **Specifications:**  
- **Input Voltage Range:** 0.7V to 5.5V  
- **Output Voltage:** Adjustable from 2V to 5.5V (fixed 3.3V or 5V versions available)  
- **Output Current:** Up to 150mA (for 3.3V output from a 1.8V input)  
- **Efficiency:** Up to 94%  
- **Switching Frequency:** 500kHz  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 16-QSOP  

### **Descriptions:**  
The MAX1672EEE+ is a high-efficiency, low-power, step-up DC-DC converter designed for battery-powered applications. It features a low start-up voltage (as low as 0.7V) and can operate from a single-cell battery. The device includes an internal N-channel MOSFET switch and requires minimal external components.  

### **Features:**  
- **Low Start-Up Voltage:** Operates down to 0.7V  
- **Internal Power Switch:** No external FET required  
- **Adjustable or Fixed Output Voltage**  
- **Low Quiescent Current:** 16µA (typical)  
- **Pulse-Frequency Modulation (PFM) for High Efficiency at Light Loads**  
- **Undervoltage Lockout (UVLO) Protection**  
- **Overcurrent Protection**  

This device is commonly used in portable electronics, medical devices, and other low-power applications requiring efficient voltage conversion.
