NUD4001 Datasheet (ON Semiconductor) - High Current LED Driver

NUD4001, High Current LED Driver

Pin Symbol Description 1 Vin Positive input voltage to the device 2 Boost This pin may be used to drive an external transistor as described in the App Note AND8198/D.

3 Rext An external resistor between Rext and Vin pins sets different current levels for different application needs 4 5, 6

DATA SHEET www.onsemi.com High Current LED Driver NUD4001, NSVD4001 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.
