Hi Khyarul,
Changing the frequency through hardware is much more difficult than doing so through firmware. I don't understand why you need to do so.

Yes, the duty cycles of both the phases should be the same for current balancing.
Since the gate driver in TIDA-00120 requires bootstrap bias for the high side MOSFET, you can't get 100% duty cycle operation. The maximum duty cycle has to be limited to around 95% to allow sufficient time for the bootstrap to charge.
