The power supply accepts a logic collector level which will disable/enable
all the output voltages. As the logic level is low, output voltages are enable;
As the logic level is high, output voltages are disable. The definition of
logic low/high level is as:
High Level: 2.50V ~ 5.25V while sourcing 0.4mA maximum
Low Level: 0.0V ~ 0.50V while sinking 5.0mA maximum

2.3.2 PS_ON#
The power supply provides an internal pull-up to TTL high. The power supply
also provides denounce circuitry on PS_ON# to prevent it from oscillating
on/off at startup when activated by a mechanical switch. The DC output enable
circuitry is SELV-complaint.
VIL, Input Low Voltage 0.0V 0.8V

Min. Max.
2.3.3 +5VSB
The +5VSB is capable of delivering a maximum of 2.5A at +5V ±5% to external
circuit. The power supply +5VSB is with overcurrent protection.
2.3.4 Power-on Time
The power-on time is less than 100ms (T1 < 100ms). The +5VSB has a
power-on time of two seconds maximum after application of valid AC
voltages. (Figure 1)
2.3.5 Rise time
The output voltages rise from ≤ 10% of nominal to within the regulation ranges
within 0.2ms to 25ms ( 0.2ms ≤ T2 ≤ 25ms). (Figure 2)
2.3.6 Overshoot at Turn-on / Turn-off
Any overshoot at turn on or turn off is under 10% of the nominal DC
output voltage with further stipulation that all DC outputs are within their
specified DC voltage ranges before the generation of the power good
signal. Additionally, no voltage may undershoot or overshoot once the
power good signal has been asserted.
2.3.7 Reset after Shutdown
The power supply latches into a shutdown state because of a fault condition
on its outputs, the power supply returns to normal operating after the fault
has been removed and the PS_ON# (or AC input) has been cycled OFF/ON
with a minimum OFF time of 1 second.

2.4 Output Protection
Each DC output is protected from over voltage, over current and short circuit. The
following sections include the details for these protection mechanisms.
2.4.1 Over voltage Protection
The overvoltage sense circuitry and reference reside in packages that are
separate and distinct from the regulator control circuitry and reference. No
single point fault is able to cause a sustained overvoltage condition on any
or all outputs. The power supply provides latch-mode overvoltage
protection defined as:
+5V output is between 5.74V to 7V
+12V output is between 13.4V to 15.6V
+3.3V output is between 3.76V to 4.8V
2.4.2 Over Current Protection
Spire Corp.
The power supply should provide +5V, +3.3Vand +12V OCP and should
shutdown of each output power. For testing purposes, the overload currents of
each tested output rail should be ramped at a minimum rate of 10A/sec.
2.4.3 Short-circuit Protection
The short circuit placed on +3.3V, +5V, + 12V, –12V and 5Vs output shall
cause no damage and the power supply shall shut down or latch.
3 Mechanical
3.1 AC Connector
The AC input receptacle is an IEC 320 type or equivalent. In lieu of a dedicated
switch, the IEC 320 receptacle may be considered the mains disconnect.
