NUD4001, NSVD4001 High Current LED Driver This device is designed to replace discrete solutions for driving LEDs in low voltage ACDC 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, NUD4001, NSVD4001 MAXIMUM RATINGS (T = 25C unless otherwise noted) A Rating Symbol Value Unit Continuous Input Voltage V 30 V in Nonrepetitive Peak Input Voltage (t 1.0 ms) V 60 V p Output Current I 500 mA out (For V 2.2 V) (Note 1) drop Output Voltage V 28 V out Human Body Model (HBM) ESD 1000 V Stresses exceeding Maximum Ratings may damage the device.
