Description and Introduction

High-Power LED Driver with Integrated High-Side LED Current Sense and PWM Dimming MOSFET Driver The MAX16834AUP+T is a high-brightness LED (HB LED) driver from Maxim Integrated (now part of Analog Devices). Below are its key specifications, descriptions, and features:

### **Manufacturer:**  
MAXIM (now Analog Devices)  

### **Part Number:**  
MAX16834AUP+T  

### **Description:**  
The MAX16834AUP+T is a step-down (buck) LED driver designed for driving high-brightness LEDs in automotive, industrial, and general lighting applications. It operates over a wide input voltage range and provides constant current to the LED string.  

### **Key Features:**  
- **Input Voltage Range:** 4.5V to 40V  
- **Output Current:** Adjustable up to 1.5A  
- **Switching Frequency:** Adjustable (100kHz to 1MHz)  
- **Efficiency:** Up to 95%  
- **PWM Dimming Control:** Supports high-frequency PWM dimming  
- **Analog Dimming Control:** Adjustable via external DC voltage  
- **Thermal Foldback:** Protects LEDs from overheating  
- **Open-LED Protection:** Detects and responds to LED open-circuit conditions  
- **Undervoltage Lockout (UVLO):** Ensures proper startup  
- **Package:** 20-pin TSSOP  

### **Applications:**  
- Automotive lighting (headlights, DRLs, interior lighting)  
- Industrial lighting  
- Architectural lighting  
- General-purpose LED drivers  

This device integrates protection features and flexible dimming options, making it suitable for demanding LED applications.
