LTC2974 PWRGD pin assert delay

Hi,Support team

I'm evaluating DC1978A(LTC2974 demo board kit).

Regarding PWRGD pin,There seems to be a delay of  >140 msec after all power rails goes up.

I tried "Mfr_config_all_pwrgd_off_uses_uv = 1" and "MFR_POWERGOOD_ ASSERTION_DELAY = 0ms",

and It was confirmed that the assertion time changed, but it did not become less than 140ms.

Can the LTC2974 shorten the assertion time any further?

Best regards,
