The device can support reverse current operation (the current flows from VOUT pin to VIN pin) in FPWM mode. If the output feedback voltage on the FB pin is higher than the reference voltage, the module regulation forces a current into the input capacitor. The reverse current operation is independent of the VIN voltage or VOUT voltage ratio, hence it is possible on all device operation modes boost, buck, or buck-boost.
