Description and Introduction

-5V,-12V,-15V, and Adjustable Inverting Current-Mode PWM Regulators The MAX759EWE is a high-efficiency, step-up DC-DC switching regulator manufactured by Maxim Integrated (now part of Analog Devices). Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Input Voltage Range:** 3V to 16V  
- **Output Voltage:** Adjustable from 5V to 28V (fixed 12V version also available)  
- **Output Current:** Up to 750mA (depending on input/output conditions)  
- **Switching Frequency:** 500kHz  
- **Efficiency:** Up to 90%  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 16-pin Wide SOIC (WE)  

### **Descriptions:**
- The MAX759EWE is a monolithic, current-mode PWM regulator designed for step-up (boost) applications.  
- It includes an internal N-channel power MOSFET switch for high efficiency.  
- The device features low quiescent current (typically 3.5mA) and shutdown mode (1µA typical).  
- It is suitable for battery-powered applications, portable devices, and industrial systems requiring a regulated high-voltage output.  

### **Features:**
- **Adjustable Output Voltage** (via external resistors)  
- **Internal Power MOSFET Switch** (reduces external component count)  
- **Current-Mode Control** for improved transient response and stability  
- **Low Battery Detector** (with adjustable threshold)  
- **Soft-Start Function** to limit inrush current  
- **Undervoltage Lockout (UVLO)** ensures proper operation under low input conditions  
- **Thermal Shutdown Protection** prevents overheating  

The MAX759EWE is optimized for compact designs requiring high efficiency and reliable power conversion.
