DA9389 Multimode Switched Capacitive Divider General Description The DA9389 is a bi-directional switched capacitor converter capable of up to 6A output current and targeting 2S or 3S battery-powered applications. When a mobile device is connected to any USB input voltage between 4 V and 13.5 V, the DA9389 can be used in current multiplier (voltage divider) mode to half the voltage applied to the V2X pin and double the available current to the system. It can also be configured to forward BYPASS and supply the V2X pin voltage directly to the system. In capacitive voltage multiplier (current divider) mode, the input voltage range (V1X pin) supports a 1S Li-Ion or Li-Polymer battery pack, or any input voltage between 2.5 V and 6.
