Description and Introduction

Two-Phase Desktop CPU Core Supply Controllers with Controlled VID Change The MAX1938EEI-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 based on factual information:

### **Specifications:**
- **Manufacturer:** Maxim Integrated (MAMIX)  
- **Package:** 28-pin QSOP (EEI)  
- **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 (fixed)  
- **Efficiency:** Up to 95%  
- **Operating Temperature Range:** -40°C to +85°C  
- **Control Method:** Current-mode PWM  

### **Descriptions:**  
The MAX1938EEI-T is a synchronous step-down DC-DC converter optimized for high efficiency and compact designs. It integrates high-side and low-side MOSFETs, reducing external component count. The device operates in pulse-width modulation (PWM) mode for stable performance across varying loads.  

### **Features:**  
- **Integrated Power MOSFETs:** Reduces external component requirements.  
- **Adjustable Output Voltage:** Set via external resistors.  
- **Low Quiescent Current:** 100µA (typical) in shutdown mode.  
- **Soft-Start Function:** Limits inrush current during startup.  
- **Thermal Shutdown Protection:** Prevents overheating.  
- **Short-Circuit Protection:** Enhances reliability.  
- **Synchronous Rectification:** Improves efficiency.  

This information is strictly based on the manufacturer's datasheet.
