Description and Introduction

High-Efficiency, 26V Step-Up Converters for Two to Six White LEDs The MAX1561ETA-T is a high-efficiency, step-up DC-DC converter manufactured by **MAXIM Integrated** (now part of Analog Devices). Below are its key specifications, descriptions, and features based on Ic-phoenix technical data files:

### **Specifications:**  
- **Input Voltage Range:** 0.7V to 5.5V  
- **Output Voltage Range:** Adjustable from 2.5V to 5.5V (fixed or externally set)  
- **Output Current:** Up to **600mA** (depending on input/output conditions)  
- **Switching Frequency:** **1MHz** (fixed)  
- **Efficiency:** Up to **95%**  
- **Package:** **8-pin TDFN (3mm x 3mm)**  
- **Operating Temperature Range:** **-40°C to +85°C**  
- **Shutdown Current:** **<1µA**  

### **Descriptions:**  
The MAX1561ETA-T is a **boost (step-up) DC-DC converter** optimized for **low-input-voltage applications**, such as single-cell or dual-cell alkaline/NiMH battery-powered devices. It integrates a **synchronous rectifier** for high efficiency and includes **soft-start** and **undervoltage lockout (UVLO)** protection.  

### **Features:**  
- **True Shutdown Mode** (disconnects load from input)  
- **Internal Synchronous Rectifier** (improves efficiency)  
- **Adjustable or Fixed Output Voltage** (factory preset options)  
- **Low Quiescent Current:** **30µA** (typical)  
- **Overcurrent and Thermal Protection**  
- **Small Footprint** (suitable for space-constrained designs)  

This device is commonly used in **portable electronics, USB power supplies, and energy-harvesting applications**.

- **Package:** 8-pin TDFN (3mm x 3mm)  

### **Descriptions:**  
The MAX1561ETA-T is a compact, high-efficiency, step-up DC-DC converter optimized for low-input-voltage applications. It integrates a synchronous rectifier to improve efficiency and reduce external component count.  

### **Features:**  
- **Low Start-Up Voltage:** Operates down to 0.7V  
- **Synchronous Rectification:** Improves efficiency and eliminates the need for an external diode  
- **Adjustable Output Voltage:** Set via external resistors  
- **Low Quiescent Current:** 35µA (typical)  
- **Internal Soft-Start:** Reduces inrush current  
- **Thermal Shutdown Protection:** Prevents overheating  
- **Undervoltage Lockout (UVLO):** Ensures proper operation
