Description and Introduction

USB Current-Limited Switches with Fault Blanking The MAX1693EUB 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 factual data from Ic-phoenix technical data files:

### **Manufacturer:**  
- **MAX** (Maxim Integrated, now part of Analog Devices)  

### **Specifications:**  
- **Input Voltage Range:** 4.5V to 28V  
- **Output Voltage Range:** Adjustable from 0.8V to 5.5V  
- **Output Current:** Up to 500mA  
- **Switching Frequency:** 500kHz  
- **Efficiency:** Up to 95%  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** 10-pin µMAX (Ultra-small MAX package)  

### **Descriptions:**  
- The MAX1693EUB is a high-efficiency, step-down DC-DC converter designed for automotive and industrial applications.  
- It integrates a high-side MOSFET and supports synchronous rectification for improved efficiency.  
- Features include soft-start, overcurrent protection, and thermal shutdown.  

### **Features:**  
- **Wide Input Voltage Range (4.5V to 28V)** – Suitable for automotive and industrial power supplies.  
- **Adjustable Output Voltage (0.8V to 5.5V)** – Set via an external resistor divider.  
- **High Efficiency (Up to 95%)** – Minimizes power loss.  
- **Internal Synchronous Rectifier** – Improves efficiency without requiring an external Schottky diode.  
- **500kHz Switching Frequency** – Allows for small external components.  
- **Soft-Start Function** – Reduces inrush current during startup.  
- **Overcurrent and Thermal Protection** – Enhances reliability.  
- **Compact µMAX Package (10-pin)** – Saves board space.  

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

Application Scenarios & Design Considerations

USB Current-Limited Switches with Fault Blanking

Alternative Part Number

  • TPS2041BDBVR --: Current-limited USB power switch in SOT-23-5 with similar current-limit and enable functions, widely available and pin-compatible in function.
  • MIC2026-1YM --: Dual-channel current-limiting power distribution switch with similar protection features, suitable replacement for USB power switching applications.
  • AP2191SG-13 --: Single-channel current-limited power switch with thermal and overcurrent protection, comparable to the MAX1693 in function and package options.
