Linear Current Regulator and Controller for
Automotive LED Rear Combination Lamps
The NCV7680 consists of eight linear programmable constant
current sources. The part is designed for use in the regulation and
control of LED based Rear Combination Lamps for automotive
applications. System design with the NCV7680 allows for two
brightness levels, one for stop and one for tail illumination, or optional
PWM control can also be implemented.
Discrete LED brightness levels are easily programmed (stop current
value, tail duty cycle value) optional external ballast FET allows for
power distribution on designs requiring high currents. Set back power
limit reduces the drive current during overvoltage conditions. This is
most useful for low current applications when no external FET is used.
