Power Supply
4.6.1 Input Supply Rating
The SBC-LX2160A system is powered by an ATX/SFX PSU with at least the
following typical ratings:
Typical Input Voltage Operating Range:
(for ATX Standard supply)
100V - 240V AC
Nominal Output Supply Voltages and minimum
currents needed for SPC-LX2160A:
12V ±5%/ 20A DC
5V ±5%/ 10A DC
3.3V ±5% / 10A DC
All output voltages should startup monotonically within 20ms.
The PSU should not exceed a maximum ripple and noise on its voltage rails over
the 10 Hz to 20 MHz frequency band of:
Maximum ripple and noise
12V max. 120mVpp
5V max. 50mVpp
3.3V max. 50mVpp
Additional filters on the SBC-LX2160A with a high bandwith integrated filter
network (BNX028-01) and capacitve buffer (up to 3.300uF for each voltage rail is
allowed by specification) are included to further dampen PSU induced noise and
rippe to the unit. For more detaillied information on current ATX and other
formfactors power supplies see:
Intel Design Guide, Desktop Platform Form Factors power Supply (June 2018
Revision 002).
