Description and Introduction

High-Efficiency, 26V Step-Up Converters for Two to Six White LEDs The MAX1561ETA+ is a high-efficiency, step-up DC-DC converter manufactured by **MAXIM Integrated**.  

### **Specifications:**  
- **Input Voltage Range:** 0.7V to 5.5V  
- **Output Voltage:** Adjustable from 2.5V to 5.5V  
- **Output Current:** Up to 300mA (depending on input/output conditions)  
- **Switching Frequency:** 1MHz (typical)  
- **Efficiency:** Up to 95%  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 8-pin TDFN (3mm x 3mm)  

### **Descriptions:**  
The MAX1561ETA+ is designed for battery-powered applications requiring a regulated voltage higher than the input supply. It integrates a synchronous rectifier for improved efficiency and includes a low-battery detector.  

### **Features:**  
- **True Shutdown Mode** (disconnects load from input)  
- **Low Quiescent Current:** 30µA (typical)  
- **Internal Synchronous Rectifier** (eliminates external diode)  
- **Low-Battery Detector** (adjustable threshold)  
- **Soft-Start** (reduces inrush current)  
- **Thermal Shutdown Protection**  

This device is commonly used in portable electronics, energy harvesting, and low-voltage power supplies.
