Power Sub-system
All outputs are measured with reference to the return remote sense signal (ReturnS). The 3.3V
and 5V outputs are measured at the remote sense point; all other voltages are measured at the
output harness connectors.

4.2.2.5 DC / DC Converters Dynamic Loading
The output voltages remain within limits specified for step loading and capacitive loading as
specified in the following table. The load transient repetition rate is tested between 50 Hz and 5
kHz at duty cycles ranging from 10%-90%. The load transient repetition rate is only a test
specification. The Δ step load may occur anywhere between MIN load and MAX load conditions.

4.2.2.6 DC / DC Converter Capacitive Loading
All outputs of the DC / DC converter are stable and meet all requirements with the following
capacitive loading ranges.
Note: Refer to the Power Supply specification for the equivalent data on +12V and +5VSB
output.
