within regulation limits.
T Delay from PSON# deactivate to PWOK being
pson_pwok
de-asserted.
T Delay from output voltages within regulation
pwok_on
limits to PWOK asserted at turn on.
T Delay from PWOK de-asserted to output
pwok_off
voltages dropping out of regulation limits.
T Duration of PWOK being in the de-asserted
pwok_low
state during an off/on cycle using AC or the
PSON signal.
T Delay from 12VSB being in regulation to O/Ps
sb_vout
being in regulation at AC turn on.
T Time the 12VSB output voltage stays within
12VSB_holdup
regulation after loss of AC.
* The 12VSBoutput voltage rise time shall be from 1.0ms to 25ms.

Protection Circuits

Protection circuits inside the power supply causes only the power supply's main outputs to
shut down. If the power supply latches-off due to a protection circuit tripping, an AC cycle OFF
for 15sec and a PSON# cycle HIGH for one second are able to reset the power supply.
