Closed Loop Stability

The power supply is unconditionally stable under all line/load/transient load conditions, including

capacitive load ranges. A minimum of 45 degrees phase margin and -10dB-gain margin are

required. Closed-loop stability is ensured at the maximum and minimum loads, as applicable.

2.5.8.9

Residual Voltage Immunity in Standby Mode

The power supply is immune to any residual voltage placed on its outputs (typically a leakage

voltage through the system from standby output) up to 500mV. There is neither additional heat

generated, nor stress of any internal components with this voltage applied to any individual

output, and all outputs simultaneously. It also does not trip the protection circuits during turn on.

The residual voltage at the power supply outputs for no load condition does not exceed 100mV

when AC voltage is applied.

2.5.8.10

Common Mode Noise

The common mode noise on any output does not exceed 350mV pk-pk over the frequency band

of 10Hz to 30MHz.

2.5.8.11

Soft Starting

The power supply contains a control circuit that provides monotonic soft start for its outputs

without overstress of the AC line or any power supply components at any specified AC line or

load conditions. There is no requirement for rise time on the 5Vstby but the turn on/off is

monotonic.

2.5.8.12

Pre-set Power-on Requirement

When the power supply turns on, the system loading maybe very light before it comes out of

reset. Under these conditions, the power supply's output voltage regulation may be relaxed to

+/-10% on the 3.3V and 5V rails and +10/-8% on the +12V rails. When the power supply is

subsequently loaded, it must begin to regulate and source current without fault.
