2.3.2 Definition
The ripple voltage of the outputs shall be measured at the pins of the output connector
when terminated in the load impedance specified in figure 1. Ripple and noise are
measured at the connectors with a 0.1uF ceramic capacitor and a 10uF electrolytic
capacitor to simulate system loading.Ripple shall be measured under any condition of
line voltage,output load,line frequency,operation temperature.

2.4 Overshoot
Any overshoot at turn on or turn off shall be less 10% of the nominal voltage value, all
outputs shall be within the regulation limit of section 2.0 before issuing the power good
signal of section 4.0.
2.5 Efficiency
2.5.1 Power supply typical efficiency is 80% min under 20% Load / 50% Load / 100%
Load at nominal input voltage of 115VAC .
2.5.2 Other Low Power System Requirements
To help meet the Blue Angel*, RAL-UZ 78, US Presidential executive order 13221, future
EPA requirements, and other low Power system requirements, it is recommended that
the +5VSB standby supply should be as efficient as possible. Standby efficiency is
measured with the main outputs off (PS_ON# high state). Standby efficiency should
be greater than 50% with a minimum loading of 100mA at input 115Vac. Pin 1W with a
minimum loading of 50mA at input 230Vac.
2.6 Remote on/off control
When the logic level "PS-ON" is low, the DC outputs are to be enabled.
When the logic level is high or open collector, the DC outputs are to be disabled.

3. PROTECTION
3.1 Over-power protection
The power supply will be shutdown and latch off when output power is 110%~150%.
3.2 Over voltage protection
The over voltage sense circuitry and reference shall reside in packages that are separate
and distinct from the regulator control circuity and reference.No single point fault shall be
able to cause a sustained over voltage condition on any or all outputs.The supply shall
provide latch-mode over voltage protection as defined in Table.

+12V1DC or +12V2DC
output Minimum Nominal Maximum Unit
+12V1DC or +12V2DC
3.3 Under voltage protection
The under voltage sense circuitry and reference shall reside in packages that are separate
and distinct from the regulator control circuity and reference.No single point fault shall be
able to cause a sustained under voltage condition on any or all outputs.The supply shall
provide latch-mode under voltage protection as defined in Table.
3.4 Over Current Protection
+5VDC, +12V1DC, +12V2DC and +3.3VDC have separate over current protection circuits
to meet 240VA safety requirement.
3.5 Short circuit
An output short circuit is defined as any output impedance of less than 0.1 ohms.The
power supply shall shut down and latch off for shorting the +3.3VDC,+5VDC,or+12VDC
rails to return or any other rail. Shorts between main output rails and +5VSB shall not
cause any damage to the power supply. The power supply shall either shut down and
latch off or fold back for shorting the negative rails.+5VSB must be capable of being
shorted indefinitely,but when the short is removed,the power supply shall recover
automatically or by cycling PS_ON#.The power supply shall be capable of withstanding
a continuous short-circuit to the output without damage or overstress to the unit.

3.6 No load operation
No damage or hazardous condition should occur with all the DC output connectors
disconnected from the load.The power supply may latch into the shutdown state.
3.7 Over temperature protection
In the event of a fan failure or the vents being blocked, the power supply shall
have protection such that any over temperature condition caused by these events
shall protect the power supply from damage or abnormal and/or dangerous
operation.A shutdown of the power supply is acceptable A temperature derating
factor less than 110% for the critical components is recommended before the
power supply is shut down. Temperature derating factors higher than 110% can
be evaluated on a case by case basis.
