TIDA-00678 showcases an automotive LED tail light application (tail/stop, turn and reverse) by using TPS92630-Q1 linear LED driver powered by an upstream boost converter (TPS40210-Q1) which is directly supplied through a smart-reverse battery diode off the automotive battery voltage. The design includes EMI/EMC radiation and pulse tests conducted by CISPR25 and ISO 7637-2 and highlights potential cost savings and efficiency (power dissipation, system thermals). For a similar design with TPS92630-Q1 driven by a buck converter, see TIDA-00677.
For a similar design with TPS92630-Q1 driven directly from a car battery, see TIDA-00679.
