Efficiency
In Standby mode, +5Vsb efficiency should be greater than 50% with a minimum loading of
100mA under I/P 230Vac.
99V ~264V: 17 mSec. Minimum.
The output voltage will remain within specification, in the event that the input power is
removed or interrupted, for the duration of one cycle of the input frequency. The interruption
may occur at any point in the AC voltage cycle. The power good signal shall remain high
during this test.
For all output range voltages shall rise from 10% of nominal to within the regulation ranges
specified in Section 4.1.1 within 0.1 ms to 20 ms (0.1 ms T1 20 ms).
(10% TO 90% OF FINAL OUTPUT VALUE, @FULL LOAD)
Output short circuit is defined to be a short circuit load of less than 0.1 ohm.
In the event of an output short circuit condition on +3.3V, +5V, -12V or +12V, the power supply
will shutdown and latch off without damage to the power supply. The power supply shall
return to normal operation after the short circuit has been removed and the power switch has
been turned off for no more than 2 seconds.
