New automotive high current LED applications demand robust and low noise LED drivers

摘要

Currently, only a handful of production vehicles are offered with LED headlamps. One of the biggest challenges for automotive lighting systems designers is how to optimize all the benefits of the latest generation of HB LEDs. Arguably, the most demanding applications for driving HB LEDs are found in automotive forward lighting applications, in both DRLs and headlamps since they are subjected to the rigors of the automotive electrical environment, must deliver high power, typically between 15W to 75W, and must fit into every space, all while maintaining an attractive cost structure.
