Description and Introduction

Current-Limited Switch for Single USB Port The MAX1931EUB+T is a high-efficiency, step-down DC-DC converter manufactured by Maxim Integrated. Below are the factual details from Ic-phoenix technical data files:

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

### **Specifications:**  
- **Input Voltage Range:** 4.5V to 28V  
- **Output Voltage Range:** Adjustable from 1.25V to 5.5V  
- **Output Current:** Up to 1.5A  
- **Switching Frequency:** 500kHz  
- **Efficiency:** Up to 95%  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 10-pin µMAX (3mm x 5mm)  

### **Descriptions:**  
The MAX1931EUB+T is a synchronous buck (step-down) DC-DC converter designed for high efficiency and compact power supply solutions. It integrates both high-side and low-side MOSFETs, reducing external component count. The device features pulse-width modulation (PWM) operation for stable output regulation.  

### **Features:**  
- Integrated synchronous rectifier for high efficiency  
- Adjustable output voltage via external resistors  
- Overcurrent and thermal shutdown protection  
- Soft-start functionality to limit inrush current  
- Low dropout operation for extended battery life  
- Small footprint due to µMAX package  

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