TIDA-00779: Changing Design constraints

Part Number:TIDA-00779

Suppose I want to operate this at 90KHz, that I can do by changing the frequency setting resistor.

So for this frequency, calculation saying that we can use a half size inductor core than actual.

So the reduction in size and value of inductance will create any issue in this design?

The initial inductance of the main inductor is actually 790uH, Is this a mandatory condition to satisfy?

If I am making this initial inductance nearer to 350uH but full load inductance is as required 180uH, Is this create any issues(for higher frequency operation 90KHz)?

Thanks.
