NSL21630/1 3 Channel 200mA/CH Automotive Linear LED Driver with Thermal Balancing Datasheet (EN) 1.0 Product Overview The NSL21630/1 is an automotive-grade three-channel linear constant current LED driver, with up to 200mA current capability per channel. Wide supply voltage up to 40V enables NSL21630/1 a good fit for automotive battery directly powered application. For linear-type constant current LED driver, thermal dissipation limit is a common issue to prevent it to be applicable for larger current or more channel-counts conditions. By implementing a unique thermal balancing design, the NSL21630/1 device is able to enlarge the output current capability with an automatic power balancing loop between the output channel and the external shunt resistor.
