Abstract

The detection section is configured to detect first and second DC voltages output. The voltage adjustment section is configured to adjust each of first and second setting values to cause a corresponding one of the first and second DC voltages detected by the detection section to fall within an allowable voltage range in which a desired supply voltage to each of a sub CPU and a main CPU is set as a center value, and, write the adjusted first and second setting values in a memory as the first and second setting values at the time of re-activation of the circuit board.

First claim

1 . A voltage adjustment system comprising: a circuit board; and an adjustment device for adjusting a supply voltage to the circuit board,
wherein the circuit board includes:
an integrated circuit comprising a first core configured such that energization thereof is not interrupted during a power-saving mode, and a second core configured such that energization thereof is interrupted during the power-saving mode;
a first power supply circuit configured to produce a first DC voltage to be sup…
