There is provided a power-supply platform IC for realizing a parameter-deciding power-supply circuit, which, in order to decide a parameter of a power-supply circuit that supplies power to an electronic circuit IC (load), is connected to the electronic circuit IC (load) in place of the power-supply circuit. The power-supply platform IC includes: one or more transistor arrays that include a plurality of transistors operable as switching transistors; and a selecting circuit for selecting a transistor to be operated as a switching transistor from among the plurality of transistors, so as to control a size of the transistor that operates as a switching transistor, wherein the selecting circuit varies the size of the transistor as a parameter of the power-supply circuit, according to an external command.
