Description and Introduction

Offline and DC-DC PWM Controllers for High-Brightness LED Drivers The MAX16801BEUA+T is a high-efficiency, high-brightness LED (HB LED) driver from Maxim Integrated. Below are its specifications, descriptions, and features based on Ic-phoenix technical data files:  

### **Manufacturer:**  
MAXIM (Maxim Integrated)  

### **Specifications:**  
- **Input Voltage Range:** 4.5V to 40V  
- **Output Current:** Adjustable (up to 1A)  
- **Switching Frequency:** Adjustable (100kHz to 1MHz)  
- **Efficiency:** Up to 96%  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** 8-pin µMAX (3mm x 3mm)  

### **Descriptions:**  
The MAX16801BEUA+T is a step-down (buck) LED driver designed for high-brightness LED applications. It provides a constant current output for driving LEDs efficiently with minimal external components. The device features an integrated power MOSFET and supports PWM dimming for brightness control.  

### **Features:**  
- Wide input voltage range (4.5V to 40V)  
- Adjustable output current (up to 1A)  
- High efficiency (up to 96%)  
- Integrated power MOSFET  
- Adjustable switching frequency (100kHz to 1MHz)  
- PWM dimming control  
- Thermal shutdown protection  
- Open-LED protection  
- Small 8-pin µMAX package

Application Scenarios & Design Considerations

Offline and DC-DC PWM Controllers for High-Brightness LED Drivers

Alternative Part Number

  • LM3445MM/NOPB --: Offline LED driver controller in an MSOP-8 package with comparable input voltage range and current-mode control, a common cross for MAX16801 designs.
  • HV9910BLG-G --: Wide-input buck LED driver controller with similar PWM dimming and current-sense architecture, suitable drop-in for many MAX16801 applications.
  • AL8805W5-7 --: Compact buck LED driver with comparable drive current and dimming capability, useful when a smaller SOT-25 solution is acceptable.
