Design and Environmental Specifications
8.2.10
The maximum allowed ripple/noise output of the power supply is defined in the following table.
This is measured over a bandwidth of 0Hz to 20MHz at the power supply output connectors.
8.2.11
The power supply shall contain a control circuit that provides monotonic soft start for its outputs
without overstress of the AC line or any power supply components at any specified AC line or
load conditions. There is no requirement for rise time on the 5V Standby but the turn on/off shall
be monotonic.
8.2.12
When the power subsystem operates in a no load condition, it does not need to meet the output
regulation specification, but it must operate without any tripping of over-voltage or other fault
circuitry. When the power subsystem is subsequently loaded, it must begin to regulate and
source current without fault. Each output voltage may not be internally diode isolated. At the
same time failure in the primary side of one power supply doesn’t cause the other to shut down.
8.2.13
These are the timing requirements for the power supply operation. The output voltages must
rise from 10% to within regulation limits (T
allowed to rise from 1.0 to 70ms. The +3.3V, +5V and +12V output voltages should start to rise
approximately at 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 50ms (T
voltage shall fall out of regulation within 400msec (T
following figures show the timing requirements for the power supply being turned on and off via
the AC input, with PSON held low and the PSON signal, with the AC input applied.
Note:
The 5VSB output voltage rise time shall be from 1.0ms to 25.0ms
