sumed brick turn-off threshold is 2.7V min TTL logic high.

See power down sequencing on Page 11.

PWRGD Output Configuration

The PS10 and PS11 open drain power good outputs can be connected directly to the Enable pins of the DC/DC converter.

The internal pull-up and clamp of the DC/DC converter sets the logic High Enable/Disable voltage.
