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

Description

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.
