Description and Introduction

4A, 20ns, MOSFET Driver The MAX5078BATT+T is a DC-DC converter from Maxim Integrated (now part of Analog Devices). Below are its key specifications, descriptions, and features:

### **Manufacturer:**  
Maxim Integrated (Analog Devices)  

### **Specifications:**  
- **Input Voltage Range:** 4.5V to 5.5V  
- **Output Voltage:** Adjustable (via external resistors)  
- **Output Current:** Up to 6A  
- **Switching Frequency:** 300kHz to 1MHz (adjustable)  
- **Efficiency:** Up to 95%  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 38-Pin TQFN (7mm x 7mm)  

### **Descriptions:**  
The MAX5078BATT+T is a high-efficiency, synchronous step-down DC-DC converter designed for high-current applications. It integrates high-side and low-side MOSFETs, reducing external component count. It supports adjustable output voltage and switching frequency, making it suitable for various power supply designs.  

### **Features:**  
- **Integrated Power MOSFETs** (reduces external components)  
- **Adjustable Output Voltage** (via resistor divider)  
- **Programmable Switching Frequency** (300kHz to 1MHz)  
- **High Efficiency** (up to 95%)  
- **Overcurrent and Thermal Protection**  
- **Soft-Start Function** (prevents inrush current)  
- **Synchronous Rectification** (improves efficiency)  

This device is commonly used in industrial, telecom, and computing applications requiring high-current power conversion.  

(Note: Always refer to the official datasheet for detailed specifications and application guidelines.)

Application Scenarios & Design Considerations

4A, 20ns, MOSFET Driver

Alternative Part Number

  • UCC27517DBVR --: Single-channel low-side gate driver in SOT-23-5 with similar drive current and pin-compatible function, widely available and cost-effective.
  • FAN3100TMPX --: Single low-side gate driver in SOT-23-6 offering comparable peak output current and supply range, suitable drop-in functional replacement.
  • MCP1407-E/SN --: High-speed single gate driver with similar drive strength and SOIC package, good alternative when layout allows package change.
  • ISL8916FBZ --: Single-channel high-speed gate driver with similar voltage and current ratings, alternative when TI or onsemi parts are unavailable.
