Automotive Camera PMIC Power Supply Reference Design with Power Over Coax Filter


Design files


This reference design incorporates a power-over-coax (POC) filter network, mid-Vin synchronous step-down DC/DC converter and low-Vin power management IC (PMIC) to demonstrate typical automotive camera power within an 18 mm x 18 mm footprint. The design accepts both data and power from a coaxial cable using a Fakra connector, isolates data from the loads using a low-pass filter network and supplies sequenced output voltages that can be adjusted with external feedback resistors.

  • Support 4.5-V to 17-V input
  • User configurable voltages
  • 18-mm x18-mm footprint solution
  • POC-filter network
  • Sequenced camera sensor supplies
