2.1 Power supplies

The LS1046ARDB gets 12 V input power from an external DC power supply. The board has power supply devices that generate
secondary power supplies from the 12 V power for correct operation of the LS1046A processor, DDR4 UDIMM, PHYs, and
numerous other peripherals. The figure below shows the LS1046ARDB power supply block diagram.
