NUD4001DEVB, Evaluation Board using NUD4001 device is designed to replace discrete solutions for driving LEOs 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 LEO 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
