Hi Nagarjuna,
Typical rise / fall time of the LP8756-series PMIC or LP8752-series PMIC is around 1.5ns. Please note that it also depends on the PCB parasitics of the SW-node, but the value I provided is a typical value.
For efficiency calculations…
Hello Zirui,
You can use our Power Efficiency Estimator tool to calculate the input current.

Thanks.

Hello Bala,
SW rise time is really a system dependent parameter (not only silicon) since PCB parasitics effect this value. But typically we have seen 3ns transition time (trise+ tfall combined).

Hello Sherry,
I am not familiar with this tool. We do have the efficiency tool, found here: https://www.ti.com/tool/PEET-GUI .
Can you provide a reference or example of the type of tool that you are looking for?
Thanks and Regards,

Hi Board Designers,
Inputs related to 5V operation
You can use the PMIC Efficiency Estimator Tool (PEET) https://www.ti.com/tool/PEET-GUI to do this - select TPS6594-Q1 in the tool. The efficiency is same between the two devices.
