Description and Introduction

Dual-Output, PWM Switch-Mode Regulator (5V to ±15V or ±12V) The MAX743EWE+T is a DC-DC converter IC manufactured by Maxim Integrated. Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:

### **Specifications:**  
- **Manufacturer:** Maxim Integrated  
- **Category:** Power Management ICs  
- **Type:** DC-DC Converter  
- **Package:** 16-SOIC (0.295", 7.50mm Width)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Mounting Type:** Surface Mount

- **Input Voltage Range:** 4.5V to 30V  
- **Output Current:** Up to 1A  
- **Switching Frequency:** 100kHz (Typical)  
- **Efficiency:** Up to 90%  

### **Descriptions:**  
The MAX743EWE+T is a high-efficiency, step-down (buck) DC-DC converter designed for applications requiring a regulated output voltage from a higher input voltage. It integrates a power MOSFET and control circuitry, simplifying power supply design while delivering high efficiency and low ripple.  

### **Features:**  
- **Wide Input Voltage Range (4.5V to 30V)** – Suitable for various power sources.  
- **Adjustable Output Voltage** – Configurable via external resistors.  
- **High Efficiency (Up to 90%)** – Reduces power dissipation.  
- **Integrated Power MOSFET** – Simplifies external component requirements.  
- **Low Dropout Operation** – Maintains regulation even with small input-output differentials.  
- **Overcurrent and Thermal Protection** – Enhances reliability.  
- **Fixed 100kHz Switching Frequency** – Minimizes EMI interference.  
- **Surface-Mount Package (16-SOIC)** – Compact and suitable for PCB designs.  

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