This device is designed to replace discrete solutions for driving LEDs in AC/DC high voltage applications (up to 200 V). An external resistor allows the circuit designer to set the drive current for different LED arrays. This discrete integration technology eliminates individual components by combining them into a single package, which results in a significant reduction of both system cost and board space. The device is a small surface mount package (SO−8).
