Automotive Rear Light EMC Reference Design


Design files


The TIDA-00264 reference design is an automative rear light EMC design. This is a direct connection to battery appllication, with a total drive of 900mA LED current. The design is implemented with 3 TPS92630-Q1 devices with fault bus connection. The TIDA-00264 will help customers use the TPS92630-Q1 to design automotive rear lights and pass EMC tests.

  • Min component to pass the RI and BCI test for automotive exterior lighting
  • Verify EMC perfermance during fault bus mode
  • This deign is sub-system and was certified for TL82166  RI and BCI level2 classA
  • This design  can be relayout and used for exterior automotive LED lighting design directly
