DA9318

Current doubler delivering up to 10 A charging current, with efficiency of up to 98 % and powering up to 44 W

The DA9318 is optimized to handle high charging currents and at the same time ensure the safety of the battery and the system. It operates together with a main charger, which handles the pre-charge and constant voltage charging duties.

The current doubling is achieved with a high-efficiency capacitive divider that provides an output voltage of V_IN/2, which allows the use of standard USB Type-C^TMcables for charging currents up to 6 A. The peak efficiency of DA9318is 98 %. With maximum 8 A charging current, DA9318L variant can provide 35 W charging power, whereas the DA9318M variant provides 10 A output current and 44 W charging power.
