Key Document


This TI 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 a typical automotive camera power solution within an 18x18mm footprint. The solution 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 - 17V input
  • User configurable voltages
  • 18x18mm footprint solution
  • Power Over Coax (POC) filter network
  • Sequenced camera sensor supplies
