Description and Introduction

Low-Supply Current, Step-Up DC-DC Converters with True Shutdown The MAX1797EUA+ 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 2.5V to 5.5V (fixed or adjustable versions available)  
- **Output Current:** Up to 300mA  
- **Switching Frequency:** 500kHz  
- **Efficiency:** Up to 94%  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 8-pin μMAX (3mm x 3mm)  

### **Descriptions:**
- The MAX1797EUA+ is a high-efficiency, step-up DC-DC converter optimized for low-input-voltage applications.  
- It integrates a synchronous rectifier for improved efficiency and eliminates the need for an external Schottky diode.  
- Suitable for battery-powered devices, portable electronics, and energy-harvesting applications.  

### **Features:**
- **Low Start-Up Voltage:** Operates down to 0.7V input.  
- **Synchronous Rectification:** Enhances efficiency and reduces external component count.  
- **Adjustable/Fixed Output:** Available in fixed (2.5V, 3.3V, 5V) or adjustable output versions.  
- **Low Quiescent Current:** 25μA (typical) in shutdown mode.  
- **Internal Soft-Start:** Prevents inrush current at startup.  
- **Overcurrent and Thermal Protection:** Ensures safe operation under fault conditions.
