Description and Introduction

1A, 76V, High-Efficiency MAXPower Step-Down DC-DC Converter The MAX5035DASA is a 1A, 76V, high-efficiency, step-down DC-DC converter manufactured by Maxim Integrated. Below are its key specifications, descriptions, and features:

### **Specifications:**  
- **Input Voltage Range:** 7.5V to 76V  
- **Output Voltage Range:** Adjustable from 1.25V to 55V  
- **Output Current:** Up to 1A  
- **Switching Frequency:** 125kHz  
- **Efficiency:** Up to 94%  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** 8-pin SOIC  

### **Descriptions:**  
- The MAX5035DASA is a step-down (buck) converter designed for high-voltage applications.  
- It integrates a power MOSFET and features a fixed-frequency PWM control scheme.  
- The device is optimized for high efficiency and low power dissipation.  

### **Features:**  
- **Wide Input Voltage Range:** Supports operation from 7.5V to 76V.  
- **1A Output Current:** Capable of delivering up to 1A of continuous output current.  
- **High Efficiency:** Up to 94% efficiency for reduced power loss.  
- **Internal Power MOSFET:** Simplifies design and reduces external component count.  
- **Fixed-Frequency PWM Operation:** Ensures predictable noise performance.  
- **Thermal Shutdown Protection:** Prevents damage from overheating.  
- **Adjustable Output Voltage:** Set via external resistors.  
- **Low Quiescent Current:** 270µA typical for improved light-load efficiency.  

This information is based solely on the manufacturer's datasheet and product documentation.
