Universal LED Front Light for Automotive Applications


Design files


This reference design is an universal LED driver in which the LED current is adjustable via 4-bit IID interface. The Sepic is has a range of the following three parameters: max. 20W, max. 60V output voltage (string voltage, so less than 15LEDs), max. 1.4A LED current. The reference design has a wide input voltage from 6V to 19V.

  • Wide input operating voltage from 4.5V to 52V
  • Fixed frequency current mode control
  • Internal slope compensaion and an intergrated low-side driver
  • Programmable close-loop start stop
  • Capable of external synchronization
  • Low current disable function
