CP6105X
3.1.3 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 CP6105X.
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 power consumption of the CP6105X is approximately 10 W.
The power consumption measurement was carried out using the following testing parameters:
»
CP6105X installed in a peripheral slot
»
Front panel ports not connected
»
MXM module not installed
»
+3.3 V and 5 V main supply voltage
»
2 m/s airflow
»
Ambient temperature: 25°C
