Description and Introduction

Multi Output, Low-Noise Power Supply Controllers for Notebook Computers The MAX1631EAI+T is a high-efficiency, step-down switching regulator manufactured by Maxim Integrated. Below are its key specifications, descriptions, and features:

### **Specifications:**  
- **Input Voltage Range:** 4.5V to 30V  
- **Output Voltage Range:** Adjustable from 1.25V to 5.5V  
- **Output Current:** Up to 2A  
- **Switching Frequency:** 300kHz  
- **Efficiency:** Up to 95%  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 28-pin SSOP (Shrink Small Outline Package)  
- **Regulation Type:** PWM (Pulse-Width Modulation)  

### **Descriptions:**  
The MAX1631EAI+T is a synchronous buck (step-down) DC-DC converter designed for high-efficiency power conversion in applications such as notebook computers, portable devices, and distributed power systems. It integrates high-side and low-side MOSFET drivers, reducing external component count.  

### **Features:**  
- **Synchronous Rectification:** Improves efficiency by reducing power loss.  
- **Adjustable Output Voltage:** Set via external resistors.  
- **Soft-Start Function:** Prevents inrush current at startup.  
- **Undervoltage Lockout (UVLO):** Ensures proper operation under low input voltage conditions.  
- **Current-Limit Protection:** Safeguards against excessive output current.  
- **Thermal Shutdown:** Protects the device from overheating.  
- **Low Dropout Operation:** Maintains regulation even when input voltage is close to output voltage.  

This information is based solely on the manufacturer's datasheet for the MAX1631EAI+T.
