Description and Introduction

Low-Voltage / 400mA Step-Down DC-DC Converters in SOT23 The MAX1920EUT-T 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 Ic-phoenix technical data files:  

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

### **Specifications:**  
- **Input Voltage Range:** 2.5V to 5.5V  
- **Output Voltage Range:** Adjustable from 0.8V to VIN  
- **Output Current:** Up to 1A  
- **Switching Frequency:** 1MHz (fixed)  
- **Efficiency:** Up to 95%  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** SOT23-6  

### **Descriptions:**  
- The MAX1920EUT-T is a synchronous step-down (buck) DC-DC converter with integrated power switches.  
- It provides high efficiency and compact power conversion for portable and battery-powered applications.  
- The device includes internal compensation, reducing external component count.  

### **Features:**  
- **Synchronous Rectification:** Improves efficiency by reducing power loss.  
- **PWM/PFM Mode Operation:** Automatically switches between modes for optimal efficiency.  
- **Low Dropout Operation:** Allows 100% duty cycle for extended battery life.  
- **Soft-Start:** Prevents inrush current at startup.  
- **Overcurrent and Thermal Protection:** Enhances reliability.  
- **Small Footprint:** Suitable for space-constrained designs.  

This information is based solely on factual data from the manufacturer's documentation.
