NCV7680 Linear Current Regulator/Controller

(16 Pin SO Wide Exposed Pad Package) Pin # Label Description 1 OUT1 Channel 1 constant current output to LED. Unused pin should be grounded. 2 VP Supply Voltage Input. 3 Ballast Drive Gate drive for external power distribution PFET. Ground if not used. 4 FB Feedback Sense node for VP regul.

NCV7680 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 programme.
