NCV7691 Overview
NCV7691 Current Controller for Automotive LED Lamps The NCV7691 is a device which uses an external NPN bipolar device bined with feedback resistor(s) to regulate a current for use in driving LEDs. The target application for this device is automotive rear bination lamps. A single driver gives the user flexibility to add single channels to multichannel systems.
