NUD4011 Low Current LED Driver This device is designed to replace discrete solutions for driving LEDs in AC/DC high voltage applications (up to 200 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 NUD4011 MAXIMUM RATINGS (T = 25 C unless otherwise noted) A Rating Symbol Value Unit Input Voltage V 200 V in Output Current I 70 mA out (For V 16 V) (Note 1) drop Output Voltage V 198 V out Human Body Model (HBM) ESD 500 V Stresses exceeding Maximum Ratings may damage the device. Maximum Ratings are stress ratings only. Functional operation above the Recommended Operating Conditions is not implied. Extended exposure to stresses above the Recommended Operating Conditions may affect device reliability. 1.
