Description and Introduction

Multi-Output / Low-Noise Power-Supply Controllers for Notebook Computers The MAX1631CAI is a high-efficiency, step-down DC-DC controller manufactured by Maxim Integrated. Below are its key specifications, descriptions, and features:

### **Specifications:**  
- **Input Voltage Range:** 4V to 30V  
- **Output Voltage Range:** Adjustable from 1.25V to 5.5V  
- **Output Current:** Up to 15A (with external components)  
- **Switching Frequency:** 200kHz (fixed)  
- **Efficiency:** Up to 95%  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 28-pin SSOP (Shrink Small Outline Package)  

### **Descriptions:**  
- The MAX1631CAI is a synchronous buck controller designed for high-current, low-voltage applications.  
- It uses pulse-width modulation (PWM) for voltage regulation.  
- Suitable for powering microprocessors, DSPs, and other high-performance digital circuits.  
- Includes undervoltage lockout (UVLO) and soft-start functionality.  

### **Features:**  
- **Synchronous Rectification:** Improves efficiency by reducing power loss.  
- **Adjustable Output Voltage:** Set via external resistors.  
- **Current-Mode Control:** Provides fast transient response.  
- **Power-Good Output:** Monitors output voltage status.  
- **Overcurrent Protection:** Prevents damage during fault conditions.  
- **Low Dropout Operation:** Maintains regulation even with small input-output differentials.
