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在/2, which allows the use of standard USB Type-CTM充电电流达6 A的电缆。DA9318IS的峰值效率为98％。最大8个充电电流，DA9318L变量可以提供35 W的充电功率，而DA9318M变型提供10个输出电流和44 W充电电源。
