Description and Introduction

Multi Output, Low-Noise Power Supply Controllers for Notebook Computers The MAX1634EAI-T is a high-efficiency, step-down DC-DC converter manufactured by Maxim Integrated (now part of Analog Devices). 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 5A  
- **Switching Frequency:** 300kHz  
- **Efficiency:** Up to 95%  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 28-pin SSOP (Shrink Small Outline Package)  

### **Descriptions:**
The MAX1634EAI-T is a synchronous buck (step-down) DC-DC converter designed for high-efficiency power conversion in applications requiring high output current. It integrates power MOSFETs, reducing external component count and simplifying design. The device supports adjustable output voltage and includes features like soft-start, overcurrent protection, and thermal shutdown.

### **Features:**
- **Integrated Power MOSFETs** – Reduces external component requirements.  
- **Adjustable Output Voltage** – Set via external resistors.  
- **High Efficiency** – Up to 95% efficiency for reduced power loss.  
- **Soft-Start Function** – Limits inrush current during startup.  
- **Overcurrent Protection** – Safeguards against excessive load conditions.  
- **Thermal Shutdown** – Protects the device from overheating.  
- **Wide Input Voltage Range** – Supports operation from 4.5V to 30V.  
- **Fixed-Frequency PWM Operation** – Ensures stable performance at 300kHz.  

This information is based solely on the manufacturer's datasheet for the MAX1634EAI-T.
