Description and Introduction

Dual USB Switch with Fault Blanking **Manufacturer:** N/A  

**Part Number:** MAX1812EUB+  

### **Specifications:**  
- **Input Voltage Range:** 4.5V to 28V  
- **Output Voltage:** Adjustable (3.3V, 5V, or user-adjustable via external resistors)  
- **Output Current:** Up to 500mA  
- **Switching Frequency:** 300kHz  
- **Efficiency:** Up to 96%  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 10-pin µMAX (3mm x 5mm)  

### **Descriptions:**  
The MAX1812EUB+ is a high-efficiency, step-down DC-DC converter designed for low-power applications. It features an integrated power MOSFET and requires minimal external components. The device operates over a wide input voltage range and provides a regulated output voltage with high efficiency.  

### **Features:**  
- **Integrated Power MOSFET** – Reduces external component count.  
- **Adjustable or Fixed Output Voltage** – Supports 3.3V, 5V, or user-defined output.  
- **Low Quiescent Current** – Typically 100µA in shutdown mode.  
- **Overcurrent and Thermal Protection** – Enhances reliability.  
- **Small Footprint** – Suitable for space-constrained applications.  
- **Soft-Start Function** – Prevents inrush current at startup.  

This information is based solely on factual data from Ic-phoenix technical data files. No additional guidance or suggestions are included.

Application Scenarios & Design Considerations

Alternative Part Number

  • TPS2113A --: Pin-compatible power mux/switch with similar current rating and logic control, widely available and lower cost.
  • LTC4412 --: PowerPath controller with comparable function and small package, good drop-in for power switching applications.
  • SGM2521 --: Low-cost load switch with similar voltage/current specs, suitable alternative when supply chain availability is a concern.
  • TPS2115APW --: Pin-compatible power mux/switch with similar current rating and logic interface, widely available and often used as a drop-in replacement for MAX1812 in power path switching applications.
  • LTC4412ES6 --: Low-loss PowerPath controller with comparable function to MAX1812, suitable for automatic power source switching in portable systems.
  • FSA4157P6X --: Low-resistance analog switch with similar package and switching function, usable as a functional alternative where exact MAX1812 features are not critical.
