Automotive LED Front Lamp with Sequential Turn Animation Reference Design


Design files


This reference design is analog solution for automotive front lamp with sequential turn animation with the SEPIC topology, and this design also realizes full automotive diagnostic with low quiescent current during fault mode.

  • Automotive battery direct connection
  • Sequential turn animation without MCU
  • Supporting larger output voltage range and high power load with SEPIC topology
  • Better thermal performance than linear type solution
  • Full diagnostic and protection
  • Low quiescent current during fault mode
