Protection Features Evaluation

The OCP and OPP triggering points are set correctly, and the OTP triggering point is reasonably set given the semi-passive operation.

DC Power Sequencing

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



No problems here since the 3.3 V rail's voltage is always lower than the voltage levels of the other two rails.

EMC Pre-Compliance Testing - Average and Quasi-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.



EMI emissions are low throughout the entire frequency range the CISPR 32 standard defines.
