Protection Features Evaluation

The OCP triggering points on the minor rails are set high, which does not seem to cause any problems with load regulation and ripple suppression.

DC Power Sequencing

According to Intel's most recent Power Supply Design Guide (revision 1.4), the +12V and 5V rails must have voltages equal or greater than the 3.3V rail's output at all times—during start up and regular operation. For our first measurement, we turn the unit off and switch it back on without any load on any of the rails.

EMC Pre-Compliance Testing – Average and Peak EMI Detector Results

Electromagnetic Compatibility (EMC) is the ability of a device to operate properly in its environment without disrupting the proper operation of other close-by devices.

Electromagnetic Interference (EMI) stands for the electromagnetic energy a device emits, and it can cause problems in other close-by devices if too high.



Conducted EMI emissions are much lower than their corresponding limits.
