Description and Introduction

High-Efficiency, Quad Output, Main Power-Supply Controllers for Notebook Computers The MAX8744AETJ+ is a power management IC (PMIC) manufactured by **Maxim Integrated** (now part of Analog Devices). Below are its key specifications, descriptions, and features based on available data:

### **Specifications:**  
- **Manufacturer:** Maxim Integrated  
- **Package:** 32-TQFN (5x5)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Input Voltage Range:** 4.5V to 24V  
- **Output Voltage Range:** Adjustable (depends on configuration)  
- **Number of Outputs:** Dual (Buck Controllers)  
- **Switching Frequency:** Adjustable (typically up to 300kHz)  
- **Features:** Synchronous Buck Controllers, High Efficiency, Low Dropout  

### **Descriptions:**  
The **MAX8744AETJ+** is a dual, step-down (buck) controller designed for high-efficiency power supply applications. It supports wide input voltage ranges and provides synchronous rectification for improved efficiency. The device is suitable for applications requiring precise power management, such as industrial systems, telecom equipment, and embedded computing.  

### **Features:**  
- **Dual Synchronous Buck Controllers** – Supports two independent step-down regulators.  
- **Wide Input Voltage Range (4.5V to 24V)** – Suitable for various power sources.  
- **Adjustable Switching Frequency** – Up to 300kHz for flexibility in design.  
- **High Efficiency** – Synchronous rectification minimizes power loss.  
- **Low Dropout Operation** – Maintains regulation even when input voltage approaches output.  
- **Programmable Soft-Start** – Reduces inrush current during startup.  
- **Overcurrent & Thermal Protection** – Enhances system reliability.
