High Current LED Driver

This device is designed to replace discrete solutions for driving

LEDs in low voltage DC applications 5V, 12V or 24V. 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 & board space. The device

is a small surface mount package (SO–8).
