Item
Tsb_on_delay Delay from AC being applied to 5VSB being within
regulation.
T ac_on_delay Delay from AC being applied to all output voltages being
within regulation.
Tvout_holdup Time all output voltages stay within regulation after loss
of AC.
Tpwok_holdup Delay from loss of AC to de-assertion of PWOK.
Tpson_on_delay Delay from PSON
regulation limits.
T pson_pwok Delay from PSON
Tpwok_on Delay from output voltages within regulation limits to
PWOK asserted at turn on.
T pwok_off Delay from PWOK de-asserted to output voltages (3.3V,
5V, 12V, -12V) dropping out of regulation limits.
Tpwok_low Duration of PWOK being in the de-asserted state during
an off/on cycle using AC or the PSON signal.
Tsb_vout Delay from 5VSB being in regulation to O/Ps being in
regulation at AC turn on.
T5VSB_holdup Time the 5VSB output voltage stays within regulation
after loss of AC.
