NXP provides a new
level of flexibility &
scalability
OVERVIEW
LED technology has evolved to enable advanced
automotive lighting applications by providing small form
factors, higher power levels, longer lifetime and lower
power consumption. Intelligent LED applications such as
Glare Free High Beam, Adaptive Driving Beam, Dynamic
Signaling and Rear lighting, make our roads safer to drive.
These systems require efficient, robust, flexible & scalable
cost effective electronics to enable the full benefits of LEDs
in automotive applications.
NXPs highly integrated LED Drivers and Controllers are
specifically designed to maximize the performance and
efficiency of lighting electronics. The ICs combine our deep
understanding of LED performance with our world-class
automotive A-BCD mixed-signal high voltage technology.
