TIDA-00679 TI reference design demonstrates a solution for automotive LED taillight applications (tail/brake lights, turn signals, reverse lights). This reference design uses the TPS92630 linear LED driver, which is powered directly from the car battery through a smart battery reverse diode. The design offers the potential for cost savings and efficiency through low power dissipation and improved system thermal performance. The reference design also includes CISPR25 testing, pulse testing (per ISO 7637-2), and EMI/EMC radiated and conducted emissions testing.
See TIDA-00677 for a similar design using the TPS92630-Q1 driven by a buck converter .
See TIDA-00678 for a similar design driven by a boost converter .
