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.
Table 42. Output Voltage Timing
Item Description MIN MAX Units
Tvout_rise Output voltage rise time from each main output. 5.01 701 msec
Tvout_on All main outputs must be within regulation of each
other within this time.
50 msec
T vout_off All main outputs must leave regulation within this
time.
400 msec
1. The 5VSB output voltage rise time shall be from 1.0 ms to 25 ms.
