High Current LED Driver

This device is designed to replace discrete solutions for driving

LEDs in low voltage AC−DC applications 5.0 V, 12 V or 24 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).
