TIDA-00677 showcases an automotive LED tail light application (tail/stop: turn and reverse) by using the TPS92630-Q1 linear LED driver supplied by an upstream buck converter (TPS65321-Q1) which is directly supplied through a smart-reverse battery diode off the automotive battery voltage. The design has also been subjected to EMI/EMC radiation and pulse tests according to CISPR25 and ISO 7637-2. More information regarding potential cost savings and efficiency (power dissipation and system thermals) can be found in the user guide. For a similar design driven by a boost converter: see TIDA-00678. For a similar design driven directly from a car battery: see TIDA-00679.
