Abstract
A system in the memory card for converting the input voltage is used to provide the most suitable voltage for the internal devices. The input voltage from external device is limited by association and specification, so is not truly suitable to the voltage demand of the internal devices. This problem could cause the power loss and reduce aging of the internal devices. The present system convert the input voltage for the voltage demand of the internal devices by switching boost-up or step-down, so as to increase the power efficiency, the operation time and having more different choices in internal devices.
