Description and Introduction

5 V, high-performance, single-ended, current-mode PWM controller The MAX5071BAUA is a high-voltage, current-mode DC-DC converter from Maxim Integrated (now part of Analog Devices). Below are its specifications, descriptions, and features based on factual data:

### **Specifications:**  
- **Input Voltage Range:** 4.5V to 40V  
- **Output Voltage Range:** Adjustable (depends on external components)  
- **Switching Frequency:** 500kHz (fixed)  
- **Output Current:** Up to 500mA (depends on configuration)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 8-pin µMAX (UA package)  
- **Efficiency:** Up to 90%  
- **Duty Cycle:** Up to 100% (low dropout operation)  

### **Descriptions:**  
- The MAX5071BAUA is a step-down (buck) DC-DC converter with integrated high-side and low-side MOSFETs.  
- It operates in current-mode control for improved transient response and stability.  
- Designed for high-voltage applications, it supports input voltages up to 40V.  
- The device includes features like soft-start, cycle-by-cycle current limiting, and thermal shutdown for protection.  

### **Features:**  
- **Wide Input Voltage Range (4.5V to 40V)**  
- **Integrated Power MOSFETs** (reduces external component count)  
- **500kHz Fixed Switching Frequency**  
- **Current-Mode Control** for fast transient response  
- **Adjustable Output Voltage** (via external resistors)  
- **Soft-Start Function** to limit inrush current  
- **Cycle-by-Cycle Current Limiting**  
- **Thermal Shutdown Protection**  
- **Low-Dropout Operation** (100% duty cycle)  
- **Compact µMAX Package** (saves board space)  

This information is strictly based on the manufacturer's datasheet and technical documentation.
