Description and Introduction

65V, low-quiescent-current, high-voltage linear regulator with mP reset and watchdog timer The MAX5023MASA is a high-efficiency, step-up DC-DC converter manufactured by Maxim Integrated (now part of Analog Devices). Below are its key specifications, descriptions, and features:

### **Specifications:**  
- **Input Voltage Range:** 2.7V to 5.5V  
- **Output Voltage Range:** Adjustable up to 28V  
- **Output Current:** Up to 100mA  
- **Switching Frequency:** 500kHz  
- **Efficiency:** Up to 90%  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 8-pin SOIC  

### **Descriptions:**  
The MAX5023MASA is a low-power, step-up DC-DC converter designed for applications requiring a regulated high voltage from a low-voltage input. It integrates a power MOSFET and a synchronous rectifier for improved efficiency. The device is suitable for battery-powered systems, LCD bias supplies, and other portable applications.  

### **Features:**  
- **Integrated Power MOSFET:** Simplifies design and reduces external components.  
- **Synchronous Rectification:** Enhances efficiency.  
- **Low Quiescent Current:** 100µA (typical) for improved battery life.  
- **Adjustable Output Voltage:** Set via external resistors.  
- **Thermal Shutdown Protection:** Prevents damage from overheating.  
- **Soft-Start Function:** Reduces inrush current during startup.  
- **Small Footprint:** 8-pin SOIC package for space-constrained applications.
