Reference design for automotive camera PMIC power supply
This Texas Instruments 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.
