Hello Field,
I'm unable to get your answer,
How we will get the Rise time & fall time with the help of Time period.
It was Depends on the Gate charge and Gate drivers right?

Can you please elaborate?

Thanks,
K.Nagarjuna

Hi Nagarjuna,

I believe I have the correct information, but have reached out to management to make sure that it is correct, and that I am able to share it publicly.

Thanks,

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 you can use our https://www.ti.com/tool/PEET-GUI.

Best Regards,
