approximately at the same time. All outputs rise monotonically. Each output voltage reach
regulation within 50ms (T
vout_on
) of each other during turn on the power supply. Each output
voltage fall out of regulation within 400ms (T
vout_off
) of each other during turn off. Table 45 shows
the timing requirements for the power supply being turned on and off by the AC input, with
PSON held low and the PSON signal, with the AC input applied. All timing requirements are met
for the cross loading condition in Table 39.
