9. Usage without Output Converter
If there is a computer system sourced, which allows a variable input voltage, then the output
converter is not necessary.
The output voltage of the Smart Battery System Manager (V_DCOUT) can be directly used and it can
be conntected at the terminal X4. The range of that voltage starts at the lowest possible voltage of
the batteries and ends at the highest input voltage (=28V) or the output voltage of the input buck-
boost converter, when used (=19V).
10. Other ATX Voltages
There is an interface for the user on the SBS MARS to implement the missing ATX voltages when
necessary. A suitable converter can be used here to create the regarding voltages.
Additionally the external converter can be enabled by an enable signal from the CPLD to create the
behaviour of a standard ATX power supply.
The connector X10 offers the possibility to connect a converter for +3.3V. If such a converter is
used, the power jumper must be changed from R85 to R86.
The connector X11 offers the possibility to connect a converter for –5V. If such a converter is used,
the power jumper must be changed from R81 to R82.
The connector X12 offers the possibility to connect a converter for –12V. If such a converter is
used, the power jumper must be changed from R83 to R84.
The pining of the converter:
Pin Name Beschreibung
1 Vin Input voltage for the converter
2 EN enable signal from CPLD
3 GND ground
4 PGOOD Power good Signal to the CPLD
5 Vout Regarding output voltage
The connectors X10, X11 and X12 have a size of 2.54 mm.
If there are no seperated converts for this voltages and power jumpers are not changed like
described above then the voltage of +3.3V, -5V and -12V are connected to the output of the used
ATX power supply at the input side of the SBS MARS.
The output of 5V standby, 5V and 12V is in most applications sufficient, especially when a
baseboard from Kontron is used.
