2.5.8.14 Timing Requirements
The timing requirements for power supply operation are as follows. The output voltages must
rise from 10% to within regulation limits (T
vout_rise
) within 5 to 70 ms, except for 5VSB, which is
allowed to rise from 1.0 to 25 ms. The +3.3V, +5V and +12V output voltages should start to rise
approximately at the same time. All outputs must rise monotonically. Each output voltage shall
reach regulation within 50ms (T
vout_on
) of each other during turn on of the power supply. Each
output voltage shall fall out of regulation within 400msec (T
vout_off
) of each other during turn off.
The following table shows the timing requirements for the power supply being turned on and off
via the AC input, with PSON held low and the PSON signal, with the AC input applied.
