Abstract
A charging device capable of dynamically adjusting a charging power. The charging device has elements as follows. A DC-DC converter power stage is used for supplying a charging current to the rechargeable battery. A current error amplifier is used for setting a charging current adjustment signal, being fed to the DC-DC converter power stage for adjusting the charging current. A first current detecting device is used for setting the charging current signal being fed to the current error amplifier. Meanwhile, the charging current is outputted to the rechargeable battery to charge the rechargeable battery. A current detecting/comparating device is used for feedback and outputting the charge current operation signal based upon the work current and a calculated charge current signal. The charging device dynamically adjusts the charging power to increase the utility of the output power of the external power source and reduce the charging time.
