Overview

The MAX20078ATE/V+T is a high-voltage, synchronous buck LED controller designed for high-brightness automotive lighting applications. It operates from a wide 4.5V to 65V input range and utilizes a proprietary control scheme that provides ultra-fast transient response without the need for external compensation components. This AEC-Q100 qualified device supports both analog and PWM dimming, making it ideal for advanced vehicle exterior lighting systems.

Why Choose This Part

The controller eliminates the need for external compensation components, simplifying PCB layout and reducing the bill of materials. Its ultrafast-response control loop prevents overshoots and undershoots during rapid dimming or load changes, while the wide 65V input capability provides significant headroom for automotive load-dump conditions.

Applications

Automotive Front Lighting
Ideal for high-beam, low-beam, and daytime running lights (DRL) where fast response to voltage transients is required.
Adaptive Front-Lighting Systems (AFS)
Maintains current regulation while shorting or opening individual LEDs in a string, supporting dynamic matrix lighting.
High-Brightness LED Drivers
Suitable for industrial or commercial lighting requiring high-voltage input and precise current control up to 1MHz switching frequency.

Getting Started

Designers can evaluate this part using the MAX20078EVKIT evaluation kit, which provides a proven PCB layout for the 16-TQFN package. When laying out a custom board, ensure the inductor current monitor and sense resistors are placed close to the IC to minimize noise sensitivity in high-frequency switching environments.
