3.4 Electrical Specifications
3.4.1 Supply Voltage
» 8 V to 18 V wide range power supply DC in single supply mode (AT)
» 12V + 5VSB ±5% in ATX mode
Power Supply Risetime
» The input voltages rise from ≤10% of nominal to within the regulation
ranges within 0.1ms to 20ms.
» There is a smooth and continuous ramp with each DC input voltage from 10%
to 90% of its final set-point, as required in the ATX specification
Supply Voltage Ripple
» Maximum 100 mV peak to peak 0-20MHz
3.4.2 Supply Current (Windows XP SP3)
The testing performed to capture the supply current data used tested modules
mounted on a Kontron evaluation board with a mouse and keyboard connected.
The power consumption tests were executed in Windows XP (with SP3) using a
tool to stress the CPU at 100% load. The power measurement values were
captured after 15 minutes of full load or a stable CPU core temperature of
90°C. To ensure a stable die temperature, a corresponding heatsink was used
to hold the temperature under the critical trip point. All boards were
equipped with a 2x1024-MB DDR3 SDRAM with ECC. The modules were tested using
the maximum CPU frequency. For more detailed information, refer to the “Power
Consumption” diagrams on the EMD Customer section of the Kontron website.
