Description and Introduction

-5V,-12V,-15V, and Adjustable Inverting Current-Mode PWM Regulators The MAX739EWE is a step-down switching regulator manufactured by Maxim Integrated (now part of Analog Devices).  

### **Specifications:**  
- **Input Voltage Range:** 4.5V to 30V  
- **Output Voltage:** Adjustable from -2V to -15V  
- **Output Current:** Up to 600mA  
- **Switching Frequency:** 170kHz  
- **Efficiency:** Up to 85%  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 16-pin Wide SOIC (SO-16)  

### **Descriptions:**  
The MAX739EWE is a monolithic, CMOS, step-down switching regulator that provides a negative output voltage from a positive input supply. It is designed for high efficiency and compact power supply solutions.  

### **Features:**  
- **Low Dropout Operation:** Maintains regulation with input voltages close to the output.  
- **Low Quiescent Current:** Typically 1.7mA.  
- **Internal Power MOSFET:** Eliminates the need for an external switch.  
- **Current Limiting & Thermal Shutdown:** Protects the device under fault conditions.  
- **Adjustable Output Voltage:** Set via external resistors.  
- **Wide Input Voltage Range:** Suitable for various applications.  

This device is commonly used in industrial, automotive, and telecom applications requiring efficient negative voltage conversion.
