Description and Introduction

500kHz Multi-Output / Low-Noise Power-Supply Controllers for Notebook Computers The MAX1904ETJ is a step-down DC-DC converter manufactured by Maxim Integrated (now part of Analog Devices). Below are its key specifications, descriptions, and features based on Ic-phoenix technical data files:

### **Specifications:**  
- **Input Voltage Range:** 4.5V to 28V  
- **Output Voltage Range:** Adjustable from 1.25V to 5.5V  
- **Output Current:** Up to 4A  
- **Switching Frequency:** 300kHz  
- **Efficiency:** Up to 95%  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 32-pin TQFN (5mm x 5mm)  

### **Descriptions:**  
The MAX1904ETJ is a high-efficiency, step-down DC-DC converter designed for applications requiring high output current with a wide input voltage range. It integrates synchronous rectification for improved efficiency and includes internal power MOSFETs, reducing external component count.  

### **Features:**  
- **Synchronous Rectification:** Improves efficiency and reduces heat dissipation.  
- **Adjustable Output Voltage:** Set via external resistors.  
- **Internal Power MOSFETs:** Simplifies design and reduces external components.  
- **Soft-Start Function:** Prevents inrush current at startup.  
- **Overcurrent and Thermal Protection:** Enhances reliability.  
- **Low Dropout Operation:** Maintains regulation even when input voltage approaches output voltage.  

This information is strictly factual and derived from the manufacturer's datasheet.
