The NCV7680 linear regulator and controller consists of eight linear programmable constant current sources. Typical applications for this device include rear combination lamps, daytime running lights, fog lights, center high-mounted stop lamp arrays, turn signal lamps and LCD backlighting.It is capable of supporting an LED driving current of up to 75-mA/channel.
The linear regulator allows support for two brightness levels – one for stop and one for tail illumination. Optional PWM control can also be implemented if required. System designers can set the output current (global set point) with the use of one external resistor. An optional external ballast FET allows for power distribution on designs requiring high currents. Qualified to the AEC Q100 automotive standard, the device has an MSL 1 moisture resistance rating, and an operating temperature range of −40° to 150°C. ($1.70 ea/10,000 — available now.)
