PORTABLE DEVICE, CHARGING SYSTEM, AND POWER SOURCE CIRCUIT SUBSTRATE

摘要

A portable device is arranged to include a secondary battery, a driving component driven by charged power of the secondary battery, a charging unit configured to charge the secondary battery by outside power, a transformation unit (processing unit) configured to output the charged power of the secondary battery at a driving voltage of the driving component, a detection unit configured to detect the input of the outside power to the charging unit, and a switching controller configured to switch the state of the transformation unit from an operation state to a stopped state only when the input of the outside power to the charging unit is detected by the detection unit.
