LM10504: Buck1 operation depending on input / output conditions

Hi,

It would be very appreciated if you answer following questions about Buck1 from our customer.

1. How does Buck1 work when Vin <3.5V is met and Vin ≥ Vout + 1V is not met?

Is Bypass-FET Operation prioritized and not switching?

2. How does Buck1 work when Vin <3.5V and Vin ≥ Vout + 1V?
