8.2.6
The output voltages shall remain within limits specified for the step loading and capacitive
loading specified in the table below. The load transient repetition rate shall be tested between
50Hz and 5kHz at duty cycles ranging from 10%-90%. The load transient repetition rate is only
a test specification. The ∆ step load may occur anywhere within the MIN load to the MAX load
conditions.
Notes
8.2.7
The power supply shall be stable and meet all requirements with the following capacitive
loading ranges.
8.2.8
The power supply shall be unconditionally stable under all line/load/transient load conditions
including capacitive load ranges. A minimum of: 45 degrees phase margin and -10dB-gain
margin is required. Closed-loop stability must be ensured at the maximum and minimum loads
as applicable.
8.2.9
The Common Mode noise on any output shall not exceed 350mV pk-pk over the frequency
band of 10Hz to 30MHz.

Step loads on each 12V output may happen simultaneously.
For Load Range 2 (light system loading), the tested step load size should be 60% of those listed.
The +12V should be tested with 1000µF evenly split between the three +12V rails.
