The MAX20078ATE+T is a high-voltage, synchronous n-channel MOSFET controller for high-current buck LED drivers. It utilizes a proprietary average current-mode-control scheme for inductor current regulation without requiring control-loop compensation, maintaining a nearly constant switching frequency.
This device operates over a wide 4.5V to 65V input range and supports switching frequencies as high as 1MHz. It includes both analog and PWM dimming capabilities, making it suitable for applications requiring a wide dimming ratio for high contrast ratios, such as matrix lighting.
The MAX20078ATE+T is designed for automotive applications and is AEC-Q100 Qualified. It features fault detection and protection, including inductor current-limit protection, overvoltage protection, and thermal shutdown. The device is available in a space-saving 16-pin TQFN (3mm x 3mm) package and is specified for operation over the -40°C to +125°C automotive temperature range.
Key features include a 5V VCC regulator capable of delivering 10mA to external circuitry and a current monitor that provides an analog voltage proportional to the inductor current. The device also has a fault flag to indicate open and short circuits across the output.
