Maxim Integrated Product launched the MAX16831 high-voltage, high-power, constant-current LED driver with analog and PWM dimming. This LED driver integrates a floating LED current-sense amplifier and dimming MOSFET driver to minimize component count and ensure high reliability in automotive and general lighting applications that utilize high-brightness (HB) LEDs. Designed to withstand harsh operating environments, the MAX16831 operates from a 5.4V to 76V input-voltage range, thus ensuring cold-start and load-dump (up to 80V) compliance.
Providing ±5% accurate LED-current control over the entire automotive operating-temperature range, this LED driver ensures excellent brightness matching. Specifically tailored to meet the requirements of the latest front-light automotive designs, MAX16831 is ideal for high- and low-beam assemblies, adaptive front-light systems, daytime-running lights (DRLs), and fog lamps.
