P_Good
Power good signal output (Internal pull up is 10kΩ to Vsb)
Floating pin will turn off P/S (shorter pin, last-make and
first-break contact for hot plugging). This signal overrides
PS-On in disabling the Main Output
Internally tied to Vsb return
Internal 1K ohm pull-up to Vsb, (accepts open collector/
drain drive), This signal to be pulled low to turn-on power
