2.5 Efficiency
80% typical and 83.70% maximum
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.
When the logic level is high or open collector, the DC outputs are to be disabled.
3.0 PROTECTION
3.1 Over current protect
The power supply shall have current limit to prevent the +3.3V, +5V, and +12V1, +12V2,
+12V3 outputs from exceeding the values shown in the following Table. If the current limits
are exceeded the power supply shall shutdown and latch off.
+12V3 outputs from exceeding the values shown in the following Table. If the current limits
are exceeded the power supply shall shutdown and latch off.

3.2 Under voltage protection.
In an under voltage fault occurs, the supply will latch all DC outputs into a shutdown state
when +5V & +3.3V outputs under 85% of its maximum value.
3.3 Over voltage protection
The over voltage sense circuitry and reference shall reside in packages that are separate
and distinct from the regulator control circuitry 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.

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 +3.3 VDC, +5 VDC,or+12 VDC rails to
