Abstract
A power reception device utilizing non-contact power transmission causes a PMOS transistor as a switch circuit to be turned ON when a secondary battery is in a heavy-load state to form a path which bypasses a series regulator (LDO) as a power supply circuit, and supplies a charging current to the secondary battery through the bypass path. An offset may be provided between ON/OFF control threshold values of the PMOS transistor. The series regulator (LDO) may be entirely or partially set in a non-operating state when forming the bypass path.
