LED interior lighting continues to grow in popularity, not only as incandescent bulb replacement, but for maker and accent applications. We offer a variety of discrete and monolithic solutions for a full range of applications. These include simple solutions such as our two terminal constant current regulators (CCRs), which are economical, robust devices that provide an effective solution for regulating current in cost sensitive automotive LED applications. More complex solutions include LIN RGB LED drivers, that combine a LIN transceiver with a RGB LED driver and memory, providing a single-chip RGB driver intended to monitor dedicated multicolor LED applications.
