onsemi LED Driver Revision A Evaluation Board LED Driver for NUD4001DR2G for LED Driver Revision

The NUD4001 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 purpose of this evaluation board is to demonstrate the operation of the NUD4001 device for applications where the voltage difference between the input voltage and the LED's voltage is small (i.e. when a 12 V supply voltage is used to power up a LED array composed of three Luxeon 1 devices).
