Part Number: LMZ31506
The standard switching frequency is 480KHz for 1.2V output as descritpion of datasheet. But due to some reasons, I need to increase switching frequency to ~750KHz. Could I only change the value of Rrt and keep Vout and Rset not changed? Will it be any issue? Thanks.
The maximum switching frequency will depend on the input voltage. Refer to table 7 of the datasheet. If operating from a 12V input, the maximum switching frequency for 1.2V output is 630kHz. If operating from 5V input, then any switching frequency from 250kHz to 780kHz is allowed.
We are glad that we were able to resolve this issue, and will now proceed to close this thread.

In reply to J Arrigo:
Is it for either RT mode and CLK mode?
In reply to le shen:
Yes, the switching frequency range applies to both RT mode or CLK mode.
