<P>PROBLEM TO BE SOLVED: To provide an electronic apparatus with a miniaturized power supply circuit, capable of suppressing noise occurrence in the output of the power supply circuit. <P>SOLUTION: The electronic apparatus includes: a power module having a control IC, for controlling the switching of a DC-DC converter circuit of a switching system, mounted on a magnetic insulation substrate having a coil conductor, included in the DC-DC converter circuit, incorporated therein; and a printed board having a mounted power module. A plurality of DC-DC converter circuits are disposed on the printed board. Each control IC is disposed in association with each DC-DC converter circuit, and controls each associated DC-DC converter circuit on the basis of a switching frequency not mutually resonating. <P>COPYRIGHT: (C)2013,JPO&INPIT |
