Hi,

This device can't support 4V-3.3V @3A, the schematic is feasible.

Hi,

Yes, this device can support 4V->3.3V@ 2A, but it is almost close to max duty cycle, the min VIN is about 3.8V. And if the device work at light load, VIN should be larger than 5V. Please refer to below app note for the detail.
