Description and Introduction

500kHz Multi-Output / Low-Noise Power-Supply Controllers for Notebook Computers The MAX1904EAI is a power management IC manufactured by Maxim Integrated. Below are its specifications, descriptions, and features based on factual information:

### **Specifications:**  
- **Manufacturer:** Maxim Integrated  
- **Part Number:** MAX1904EAI  
- **Package:** 28-pin SSOP (Shrink Small Outline Package)  
- **Input Voltage Range:** 4.5V to 30V  
- **Output Voltage Range:** Adjustable (via external resistors)  
- **Switching Frequency:** 300kHz (fixed)  
- **Output Current:** Up to 5A  
- **Efficiency:** Up to 95%  
- **Operating Temperature Range:** -40°C to +85°C  

### **Descriptions:**  
The MAX1904EAI is a high-efficiency, step-down (buck) DC-DC converter designed for applications requiring high current and wide input voltage ranges. It integrates a synchronous rectifier to improve efficiency and reduce external component count. The device is suitable for powering processors, ASICs, and other high-performance digital loads.  

### **Features:**  
- **High Efficiency:** Up to 95% efficiency due to synchronous rectification.  
- **Wide Input Voltage Range:** Supports 4.5V to 30V input.  
- **Adjustable Output Voltage:** Configurable via external resistors.  
- **5A Output Current Capability:** Suitable for high-power applications.  
- **Fixed-Frequency Operation:** 300kHz PWM for predictable noise performance.  
- **Integrated Power MOSFETs:** Reduces external component count.  
- **Overcurrent and Thermal Protection:** Enhances system reliability.  
- **Soft-Start Function:** Prevents inrush current at startup.  

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

Application Scenarios & Design Considerations

500kHz Multi-Output / Low-Noise Power-Supply Controllers for Notebook Computers

Alternative Part Number

  • LTC3728EG --: Dual synchronous step-down controller with similar function and SSOP package, widely used as a MAX1904 cross-reference.
  • ISL6520ACBZ --: Single-phase synchronous buck controller offering comparable regulation features and a different series naming for easy distinction.
  • TPS51116PWP --: DDR/dual-rail synchronous buck controller with similar control architecture, suitable as a functional substitute in many designs.
  • LTC3728LEGN --: Dual synchronous step-down controller with similar function and pin-compatible SSOP package; widely available and well documented.
  • TPS51124RGE --: Dual-channel synchronous buck controller covering similar input/output range, good drop-in candidate for notebook power designs.
  • ISL6237IRZ --: Dual-output PWM controller for notebook power rails with comparable features and QFN package option.
