Description and Introduction

5V / Step-Down / Current-Mode PWM DC-DC Converters The MAX738AEWE is a voltage regulator manufactured by Maxim Integrated (now part of Analog Devices). Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:

### **Specifications:**  
- **Manufacturer:** Maxim Integrated (MAXIM)  
- **Part Number:** MAX738AEWE  
- **Package:** 16-pin Wide SOIC (SOIC-16)  
- **Input Voltage Range:** 5.2V to 11V  
- **Output Voltage:** +5V (fixed)  
- **Output Current:** 750mA (max)  
- **Dropout Voltage:** 1V (typical at full load)  
- **Switching Frequency:** 170kHz (typical)  
- **Efficiency:** Up to 90%  
- **Operating Temperature Range:** -40°C to +85°C  
- **Protection Features:** Overcurrent, thermal shutdown  

### **Descriptions:**  
The MAX738AEWE is a step-down (buck) switching regulator that provides a fixed +5V output from an input voltage range of 5.2V to 11V. It is designed for high efficiency and low power dissipation, making it suitable for battery-powered and space-constrained applications.  

### **Features:**  
- High-efficiency switching regulator  
- Low dropout voltage (1V typical)  
- Internal power MOSFET switch  
- Built-in current limiting and thermal shutdown  
- Low quiescent current (1.7mA typical)  
- Adjustable soft-start capability  
- Small external component count  

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