Description and Introduction

4MHz, 500mA Synchronous Step-Down DC-DC Converters in Thin SOT and TDFN The **MAX8561ETA+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:

### **Specifications:**  
- **Input Voltage Range:** 0.7V to 5.5V  
- **Output Voltage Range:** Adjustable from 1.8V to 5.5V (fixed or adjustable options)  
- **Output Current:** Up to **600mA** (dependent on input/output conditions)  
- **Switching Frequency:** **1.2MHz** (typical)  
- **Efficiency:** Up to **95%**  
- **Operating Temperature Range:** **-40°C to +85°C**  
- **Package:** **8-pin TDFN (3mm x 3mm)**  

### **Descriptions:**  
The MAX8561ETA+T is a **boost (step-up) DC-DC converter** designed for low-voltage applications, such as battery-powered devices. It integrates a **synchronous rectifier** for improved efficiency and includes **soft-start** and **undervoltage lockout (UVLO)** protection.  

### **Features:**  
- **True Shutdown Mode** – Disconnects load from input when disabled.  
- **Low Quiescent Current:** **20µA** (typical) in shutdown mode.  
- **Internal Compensation** – Simplifies design.  
- **Synchronous Rectification** – Enhances efficiency.  
- **Thermal Shutdown Protection** – Prevents overheating.  
- **Adjustable Output Voltage** (via external resistors).  

This device is commonly used in **portable electronics, medical devices, and energy-harvesting applications**.
