The TIDA-00679 TI design showcases a solution for an automotive LED tail light application (Tail/Stop, Turn, Reverse). It uses the TPS92630 linear LED driver which is directly powered through a smart reverse battery diode off the automotive battery. The design enables potential cost savings and efficiency through lower power dissipation and improved system thermals. The reference design also includes CISPR25 testing, pulse tests by ISO 7637-2 and EMI/EMC radiated and conducted emissions testing.
