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. The device is a small surface mount package (SO–8).
Features
Supplies Constant LED Current for Varying Input
Voltages External Resistor Allows Designer to Set Current – up to 500 mA Offered in Surface Mount Package Technology (SO−8) NSV Prefix for Automotive and Other Applications Requiring
Unique Site and Control Change Requirements; AEC−Q101 Qualified and PPAP Capable
Pb−Free Package is Available
