Description and Introduction

500mA, 76V, High-Efficiency, MAXPower Step-Down DC-DC Converter The MAX5033BASA+ is a high-efficiency, step-down DC-DC converter manufactured by **MAXIM Integrated** (now part of Analog Devices).  

### **Specifications:**  
- **Input Voltage Range:** 7.5V to 76V  
- **Output Voltage:** Adjustable from 1.25V to 13.2V (fixed 3.3V, 5V, or 12V options available)  
- **Output Current:** Up to 500mA  
- **Switching Frequency:** 125kHz  
- **Efficiency:** Up to 94%  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** 8-pin SOIC  

### **Descriptions and Features:**  
- **High-Voltage Input:** Operates from a wide input range, suitable for industrial and automotive applications.  
- **Internal Power MOSFET:** Includes an integrated 76V, 0.4Ω power switch.  
- **Low Quiescent Current:** 270µA typical (shutdown mode reduces current to 10µA).  
- **Thermal Shutdown and Current Limit Protection:** Ensures safe operation under fault conditions.  
- **Adjustable Soft-Start:** Reduces inrush current during startup.  
- **Fixed Frequency PWM Operation:** Provides stable performance with minimal external components.  

The MAX5033BASA+ is designed for applications requiring high input voltage and moderate output current, such as industrial power supplies, automotive systems, and telecom infrastructure.
