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.
