Description and Introduction

PLASTIC ENCAPSULATED DEVICES The MAX1973EUB is a high-efficiency, step-down DC-DC converter manufactured by Maxim Integrated. Below are the key specifications, descriptions, and features based on factual information:

### **Specifications:**  
- **Input Voltage Range:** 2.7V to 5.5V  
- **Output Voltage Range:** Adjustable from 0.8V to VIN  
- **Output Current:** Up to 500mA  
- **Switching Frequency:** 1MHz (typical)  
- **Efficiency:** Up to 95%  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 10-pin µMAX (3mm x 5mm)  

### **Descriptions:**  
- The MAX1973EUB is a synchronous step-down DC-DC converter optimized for high efficiency and compact designs.  
- It integrates both high-side and low-side MOSFETs, reducing external component count.  
- Suitable for battery-powered applications due to its low quiescent current (40µA typical).  

### **Features:**  
- **Pulse-Width Modulation (PWM) Operation** for consistent performance.  
- **Low Dropout Operation** extends battery life.  
- **Internal Soft-Start** prevents inrush current.  
- **Overcurrent and Thermal Shutdown Protection** for reliability.  
- **Adjustable Output Voltage** via external resistors.  
- **Synchronous Rectification** improves efficiency.
