Description and Introduction

Two-Phase Desktop CPU Core Supply Controllers with Controlled VID Change The MAX1937EEI+ is a high-efficiency, step-down DC-DC converter manufactured by **MAXIM Integrated** (now part of Analog Devices).  

### **Key Specifications:**  
- **Input Voltage Range:** 4.5V to 28V  
- **Output Voltage Range:** Adjustable from 1.25V to 5.5V  
- **Output Current:** Up to 500mA  
- **Switching Frequency:** 500kHz  
- **Efficiency:** Up to 95%  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 28-pin SSOP (Shrink Small Outline Package)  

### **Descriptions:**  
The MAX1937EEI+ is a synchronous buck converter with integrated power switches, designed for high-efficiency power conversion in applications requiring a compact and reliable solution. It features **PWM (Pulse-Width Modulation)** operation for optimal efficiency across varying loads.  

### **Features:**  
- **Integrated Power MOSFETs** (eliminates the need for external switches)  
- **Adjustable Output Voltage** via external resistors  
- **Low Dropout Operation** for extended battery life  
- **Soft-Start Function** to limit inrush current  
- **Overcurrent and Thermal Protection** for enhanced reliability  
- **Synchronous Rectification** for improved efficiency  

This device is commonly used in **portable electronics, industrial systems, and automotive applications** where high efficiency and compact design are critical.
