Description
The TIDA-00677 TI design is showcasing a solution for an automotive LED tail light application (Tail/Stop, Turn, 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, system thermals) can be found in the user guide. For a similar design driven by Boost Converter, please see the TIDA-00678. For a similar design driven directly from car battery, please see the TIDA-00679.directly supplied through a smart reverse battery diode off the automotive battery voltage.
