Advance Information  
Switching LED Current  
Source  
http://onsemi.com  
This integrated Switching LED Driver provides a regulated dc  
current to an LED powered from a standard automotive 12 V system.  
It is a low cost switching device which utilizes a minimal of external  
components that can be used to power high intensity LEDs for a  
number of applications.  
The NUD4021 is recommended for currents of 50 mA to 400 mA,  
while the NUD4022/NUD4023 is recommended for currents of  
300 mA to 2.0 A.
