Notes:
1. TDP is the Thermal Design Power. TDP is the sustained (DC equivalent) Power delivered at the Remote Sense Points of the
Processor. TDP = 100W.
VCore TDP < 85W
VCache TDP < 18W
VFixed TDP < 11.5W
2. Vin = 12Vdc, Ta = 25°C, Airflow = 400LFM unless otherwise noted.
3. TDC is the Thermal Design Current. TDC is the sustained (DC equivalent) Current that the processor is capable of drawing
indefinitely and defines the current to use for the voltage regulator temperature assessment.
ICore TDC < 85A max.
ICache TDC < 17A max.
IFixed TDC < 9.2A max.
4. Min load is as specified below:
ICore out min = 2.8A
ICache out min = 2.0A
IFixed out min = 0.7A
5. AC tolerance is defined as the sum of the static ripple, transient cross regulation and transient overshoot. It is measured in both
the positive and negative directions.
6. Peak Output Current
ICore 121Apk, Short term load @ 12.5% duty cycle
ICache 18Apk, Short term load @ 12.5% duty cycle
IFixed 11.04Apk, Short term load @ <1% duty cycle
7. MTBF Prediction based on 12Vdc input, 400LFM airflow, 85% of total unit output loading and component temp rise per nominal
section of 20891 stress analysis.
8. Efficiency was measured under the following conditions:
Temp = 25°C
Vin = 12V
Vcore = 1.3V @ 65A
Vcache = 1.3V @ 10A
Vfixed = 1.25V @ 2A
