2-2. AC Inrush Current
The power supply must meets inrush requirements of any rated AC voltage, during
turn on at any phase of voltage, during a single cycle AC dropout condition, during
repetitive On/Off cycling of AC, and over the specified temperature range. The peak
inrush current shall be less than the rating of its critical components (including input
fuse, bulk rectifiers, and surge limiting device).
2-3. Input Power Factor Correction ( Active PFC)
Ś
The power factor at full load shall be 0.99
at nominal input voltage.

2-4. Input Current Harmonics
When the power supply is operated in 90-264Vac of Sec. 2.1, the input harmonic
current drawn on the power line shall not exceed the limits set by EN61000-3-2
class "D" standards. The power supply shall incorporate universal power input with
active power factor correction.
2-5. AC Line Dropout
01
An AC line dropout of 17mS or less shall not cause any tripping of control signals or
protection circuits. If the AC dropout lasts longer than 17mS the power supply
should recover and meet all turn on requirements. The power supply shall meet the
regulation requirement over all rated AC voltages, frequencies, and output loading
conditions. Any dropout of the AC line shall not cause damage to the power supply.
An AC line dropout is defined as a drop in AC line to 0VAC at any phase of the AC
line for any length of time.

reference to the return remote sense (ReturnS) signal. The +5V,+3.3V, +12V, -12V and
+5VSB outputs are measure at the power supply connectors references to ReturnS. The
+5V and +3.3V is measured at its remote sense signal (+5VS, +3.3VS) located at the
signal connector.

3-3. Timing Requirements
These are the timing requirements for the power assembly operation. The output
voltages must rise from 10% to within regulation limits (Tvout_rise) within 5 to 70mS. The
+5V, +3.3V and +12V output voltages should start to rise at about the same time. All
outputs must rise monotonically. The +5V output needs to be greater than the +3.3V
output during any point of the voltage rise. The +5V output must never be greater than
the +3.3V output by more than 2.25V. Each output voltage shall reach regulation within
50 mS (Tvout_on) of each other during turn on of the power supply. Each output voltage
shall fall out of regulation within 400 mS (Tvout_off) of each other during turn off. Figure 1
and figure 2 show the turn On and turn Off timing requirement. In Figure 2, the timing is
shown with both AC and PSON# controlling the On/Off of the power supply.

3-4. Remote On/Off Control : PSON#
The PSON# signal is required to remotely turn on/off the power supply. PSON# is an
active low signal that turns on the +5V, +3.3V, +12V and -12V power rails. When
this signal is not pulled low by the system, or left open, the outputs (except the
+5VSB and V bias) turn off. This signal is pulled to a standby voltage by a pull-up
resistor internal to the power supply.
Accepts an open collector/drain input from the system.
Pull-up to VSB locted in power supply.

3-6. +5VSB (Standby)
The +5VSB output is always on (+5V Standby) when AC power is applied and power
switch is turned on.
The +5VSB line is capable of delivering at a maximum of 4A for PC board circuit to
operate.

4. Protection
Protection circuits inside the power supply shall cause only the power supply's main
outputs to shutdown. If the power supply latches off due to a protection circuit tripping,
either a AC cycle OFF for 15 sec, or PSON# cycle HIGH for 1 sec must be able to restart
the power supply.
4-1. Over Current Protection
This power supply shall have current limit to prevent the +5V, +3.3V, and +12V
outputs from exceeding the values shown in table 14. The current limit shall not trip
under maximum continuous load or peak loading as described in Table 5. The power
supply shall latch off if the current exceeds the limit. The latch shall be cleared by
toggling the PSON# signal or by cycling the AC power. The power supply shall not
be damaged from repeated power cycling in this condition. The -12V and +5VSB
outputs shall be shorted circuit protected so that no damage can occur to the power
supply.
