Wide Input Automotive Buck Reference Design


Design files


This automotive reference design has an input voltage range of 10V to 45V and provides an output voltage of 9.0V @ 150mA. It's using only ceramic capacitors on the output as well as on the input which enables the use for a wide temperature range.

  • Only Ceramic Capacitors
  • High Efficiency
  • Small Solution Size
  • High Switching Frequency
