Description and Introduction

Single-Phase, Synchronous MOSFET Drivers The MAX8791 is a high-efficiency, step-up DC-DC converter designed by Maxim Integrated (now part of Analog Devices). Below are its key specifications, descriptions, and features:

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

### **Descriptions:**  
- The MAX8791 is a compact, high-efficiency, step-up DC-DC converter optimized for driving white LEDs in small LCD backlight applications.  
- It operates over a wide input voltage range (2.5V to 5.5V) and can deliver up to 30V output.  
- The device integrates a current-mode PWM controller with an internal power MOSFET for high efficiency and reduced external component count.  

### **Key Features:**  
- **Input Voltage Range:** 2.5V to 5.5V  
- **Output Voltage Range:** Up to 30V  
- **Switching Frequency:** 1MHz (fixed)  
- **High Efficiency:** Up to 90%  
- **Integrated Power MOSFET:** Reduces external components  
- **PWM Dimming Control:** Supports wide dimming ratio  
- **Overvoltage Protection (OVP):** Protects LEDs from excessive voltage  
- **Thermal Shutdown:** Prevents overheating  
- **Small Package:** 10-pin µMAX (3mm x 3mm)  

### **Applications:**  
- LCD backlighting for portable devices  
- White LED drivers  
- Battery-powered systems  

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