Claim:
1. A power control device receiving supply of power from a power source, performing voltage conversion, and supplying loads with power, the power control device comprising: a power accumulator configured to accumulate a part of power from the power source; a first voltage converter configured to receive power from the power source and the power accumulator, perform voltage conversion to a first target voltage, and supply power with the first target voltage to a first load; a second voltage converter configured to receive power from the first voltage converter, perform voltage conversion to a second target voltage, and supply power with the second target voltage to a second load; a power source monitor configured to monitor power from the power source; and a power controller configured to lower the first target voltage to a level that the second voltage converter is capable of converting to the second target voltage when the power source monitor detects that the supply of power from the power source has stopped.
