NUD4001

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. 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 Benefits Maintains a Constant Light Output During Battery Drain One Device can be used for Many Different LED Products Reduces Board Space and Component Count Simplifies Circuit and System Designs Typical Applications Portables: For Battery Back−up Applications, also Simple Ni−CAD Battery Charging Industrial: Low Voltage Lighting Applications and Small Appliances Automotive: Tail Lights, Directional Lights, Back−up Light, Dome Light PIN FUNCTION DESCRIPTION Pin Symbol Description 1 Vin Positive input voltage to the device 2 Boost This pin may be used to drive an external tran...
