Description and Introduction

3.3V, Step-Down, Current-Mode PWM DC-DC Converters The MAX748ACWE is a precision, dual-output, step-down controller manufactured by Maxim Integrated (now part of Analog Devices). Below are the factual details about its specifications, descriptions, and features:

### **Manufacturer:**  
Maxim Integrated (Analog Devices)  

### **Part Number:**  
MAX748ACWE  

### **Package:**  
16-pin Wide SOIC (SO-16W)  

### **Description:**  
The MAX748ACWE is a high-efficiency, dual-output, step-down (buck) switching regulator controller. It is designed to generate two independently regulated output voltages from a single input supply.  

### **Key Features:**  
- **Input Voltage Range:** 4V to 30V  
- **Dual Outputs:** Two independently controlled step-down regulators  
- **Adjustable Output Voltage:** Configurable via external resistors  
- **Switching Frequency:** Up to 300kHz (adjustable)  
- **High Efficiency:** Up to 90%  
- **Current-Mode Control:** Improves transient response and stability  
- **Low Dropout Operation:** Extends battery life  
- **Soft-Start Function:** Reduces inrush current  
- **Undervoltage Lockout (UVLO):** Ensures proper operation under low input voltage  
- **Thermal Shutdown Protection:** Prevents overheating  
- **Wide Operating Temperature Range:** -40°C to +85°C  

### **Applications:**  
- Distributed power systems  
- Battery-powered devices  
- Industrial and automotive systems  
- Telecommunications equipment
