Description and Introduction

3.3V, Step-Down, Current-Mode PWM DC-DC Converters The MAX748AEWE is a voltage regulator IC manufactured by Maxim Integrated (now part of Analog Devices). Below are its key specifications, descriptions, and features based on available data:  

### **Manufacturer:** Maxim Integrated (Analog Devices)  
### **Part Number:** MAX748AEWE  

### **Specifications:**  
- **Type:** Step-Up (Boost) DC-DC Switching Regulator  
- **Input Voltage Range:** 2V to 16.5V  
- **Output Voltage:** Adjustable (up to 28V)  
- **Output Current:** Up to 300mA (dependent on input/output conditions)  
- **Switching Frequency:** 500kHz (fixed)  
- **Efficiency:** Up to 90%  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 16-pin Wide SOIC (SO-16)  

### **Descriptions:**  
The MAX748AEWE is a high-efficiency, step-up DC-DC switching regulator designed for applications requiring a higher output voltage than the input supply. It features an internal N-channel MOSFET switch, reducing external component count. The device is optimized for battery-powered systems and portable electronics where power efficiency is critical.  

### **Features:**  
- Adjustable output voltage via external resistors  
- Low shutdown current (<1µA)  
- Internal current limiting and thermal shutdown protection  
- Soft-start capability to reduce inrush current  
- Small external component count  
- Suitable for battery-powered applications
