Abstract
A charging apparatus includes a DC-DC converter for stepping down a charging input voltage, and a charging current controller having two input terminals and one output terminal. The input terminals receive a voltage based on a charging current drawn from a voltage stepped down by the DC-DC converter. The voltage at the output terminal serves as a control voltage for controlling the charging current drawn from the stepped-down voltage.
