Description and Introduction

1A, 76V, High-Efficiency MAXPower Step-Down DC-DC Converter The MAX5035BASA is a high-efficiency, step-down DC-DC converter from Maxim Integrated (now part of Analog Devices). Below are its key specifications, descriptions, and features:

### **Manufacturer:**  
- Maxim Integrated (now Analog Devices)  

### **Specifications:**  
- **Input Voltage Range:** 7.5V to 76V  
- **Output Voltage:** Adjustable from 1.25V to 55V (fixed 3.3V, 5V, 12V options available)  
- **Output Current:** Up to 1A  
- **Switching Frequency:** 125kHz  
- **Efficiency:** Up to 94%  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 8-pin SOIC  

### **Descriptions:**  
- The MAX5035BASA is a step-down (buck) DC-DC converter designed for high-voltage applications.  
- It integrates a power MOSFET switch for efficient power conversion.  
- Suitable for industrial, automotive, and telecom applications requiring stable power from a wide input range.  

### **Features:**  
- **Wide Input Voltage Range (7.5V to 76V)** – Supports high-voltage inputs.  
- **Internal Power MOSFET** – Simplifies design and reduces external component count.  
- **Adjustable/Fixed Output Voltage** – Offers flexibility in output voltage selection.  
- **High Efficiency (Up to 94%)** – Minimizes power loss.  
- **Overcurrent and Thermal Protection** – Enhances reliability.  
- **Low Quiescent Current (270µA)** – Improves efficiency in light-load conditions.  
- **125kHz Switching Frequency** – Reduces output ripple and EMI.
