Hello Nagasawa-san,
The transient is not too fast for LP8752x device. Do you have voltage overshoot/undershoot requirement in the system?
Thanks.

Hello Tomi-san
I'm sorry for delay response and lack of information.
Target voltage of over/under shoot is ±50mV.
Does LP8752x meet this spec?

Hi Nagasawa-san,
With two phase operation it is doable. With single phase it might be difficult to meet that spec. So with two bucks connected together in LP8752x it stays inside the +/-50mV window with the transient you described.
Thanks.
Best regards,
