LED lighting control reference design for machine vision

This Texas Instruments' LED lighting control reference design shows a unique approach to drive and control a string of multiple high-power LEDs. This design is aimed at industrial machine vision systems and is also ideal for other industrial or automotive lighting applications. The design enables users to program LED current and timing to allow the safe overdriving of LEDs for enhanced brightness. The design can function autonomously but can also be triggered or produce a trigger through an isolated interface. Internal circuit blocks help a wide input voltage range, a programmable input current, and input power control, as well as offering protection against reverse polarity, overvoltage and overtemperature.
