LM25085: Low VIN condition

Hi,

Pgate voltage goes from Low to High after few ms from when VIN dropped below 4.5V as attached.

Can we bring forward this rising edge?

Because we would like to drop VOUT(+5V) quickly.

Best Regards,

Kuramochi

Hi,

I am not sure if you can turn off the FET faster because the signal is probably controlled internally.
Let me double check

Thanks
