NUD4001  
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,  
which results in a significant reduction of both system cost and board  
space. The device is a small surface mount package (SO–8).
