ABSTRACT:
A power control apparatus includes a first driven circuit and a second driven circuit connected to the first driven circuit. A primary power-supply circuit produces a primary voltage from a source voltage of a battery and supplies the primary voltage to drive the first driven circuit. A secondary power-supply circuit produces a secondary voltage from the source voltage of the battery or from the primary voltage of the primary power-supply circuit, and supplies the secondary voltage to drive the second driven circuit. A control circuit outputs a power-supply control signal to the secondary power-supply circuit in response to a command signal, so that the supply of the secondary voltage to the second driven circuit by the secondary power-supply circuit is started or terminated by the power-supply control signal.
