4.1.3 Regulation
The power supply shall be unconditionally stable under line, load, unload and transient load condi-
tions including capacitive loads. The operation of the power supply must be consistent even without
the minimum load on all output lines.
Note:
All of the input voltages must be functionally coupled to each other so that if one input
voltage fails, all other input voltages must be regulated proportionately to the failed volt-
age. For example, if the +5V begins to decrease, all other input voltages must decrease ac-
cordingly. This is required in order to preclude cross currents within the CP6005(X)-SA.
Failure to comply with above may result in damage to the board or improper system oper-
ation.
Note:
If the main power input is switched off, the supply voltages will not go to 0V instantly. It
will take a couple of seconds until the capacitors are discharged. If the voltage rises again
before it has gone below a certain level, the circuits may enter a latch-up state where even
a hard RESET will not help any more. The system must be switched off for at least 10 sec-
onds before it may be switched on again. If problems still occur, turn off the main power
for 30 seconds before turning it on again.

Power Consumption
The goal of this description is to provide a method to calculate the power consumption for the
CP6005(X)-SA baseboard and for additional configurations. The processor and the memory dissipate
the majority of the thermal power.
The power consumption measurements were carried out using the following testing parameters:
»
CP6005(X)-SA installed in the system slot
»
Ethernet ports not connected
»
4 GB DDR3L SDRAM in dual-channel mode
»
+3.3 V, 5 V, and 12 V main supply voltage
»
2.5 m/s airflow
The operating systems used were uEFI Shell and Windows® 7, 64-bit. All measurements were conducted
at an ambient temperature of 25 °C. The power consumption values indicated in the tables below can
vary depending on the ambient temperature. This can result in deviations of the power consumption
values of up to 15%.
The power consumption was measured using the following the 4
