3.7 SYSTEM-VOLTAGES SUPPLIED BY THE PIP
The PIP has the possibility to supply -12 V, -5 V, 3.3 V, 5 V and 12 V to different connectors on the PIP PCB. But
there are some specialties to pay attention to:
•
-12 V, -5 V and 12 V are not generated by the PIP itself.
•
There is only a limited current available on -12 V, -5 V, 3.3 V, 5 V and 12 V system voltages (either the PCB
is not dimensioned for more current or the switching regulators don't supply more current).
•
These voltages are not fused on the internal connectors.
3.7.1 -12 V, -5 V AND 12 V
-12 V, -5 V and 12 V must be generated by a separate power supply, that supplies these voltages to the internal
power connectors J4 and J6.
You can use V
IN
(J4 pin 1-3) for the power source and 3.3V or 5V (J4 pin 3/4 or pin 1/2) for the ON/OFF signal
for these power supplies.
The maximum currents allowed for all loads on the different voltages are:

3.7.2 3.3 V, 5 V and 5 V Standby
The switching regulators on the PIP for 3.3 V and for 5 V supplies maximum 5 A for all loads not soldered down
on the PIP PCB. Also on the 5V Standby are for not soldered down devices 1 A available. So each load you add
to one of these voltages must be accumulated and the total amount of current must not exceed the below
mentioned current values.
