Hello Avi,
To answer your questions:
- An inductor will behave as a short in DC. Although it is possible to apply 3.3V at the SW node via L2 I would not recommend as it is outside the operating parameters of the part and could damage internal circuitry.
- If the High Side Gate is turned on, the power flow will enter the SW pin and be connected to the IN pin. See block diagram below.
